Numa mesma época marcada por reflexões filosóficas sobre o tempo e suas relações com o espaço, Cecília Meireles e Sophia de Mello Breyner Andresen entregaram ao mundo os seus primeiros escritos poéticos, nos quais revelam que essas mesmas reflexões não se distanciam da poesia. Ao contrário, num espaçotempo caracterizado pela transitoriedade das coisas, a poesia se apresenta como forma de equilíbrio em meio à passagem, evitando a total dispersão do ser. Assim sendo, nossa análise procura focalizar as formas que espaço e tempo assumem na poesia de ambas as escritoras, investigando a possibilidade desses \"cronotopos\" servirem à revelação da experiência humana no tempo e no espaço.In a same age marked by philosophical reflections about the time and their relations with the space, Cecília Meireles and Sofia de Mello Breyner Andresen handed over to the world their first poetic pieces of writing, in which they reveal that those same reflections is not far from poetry. The other way round, in a space-time characterized by the transiency of things, the poetry shows itself as a way of balance in the middle of the passage, avoiding the total being\'s dispersion. This being the case, our analysis tries to focus the forms that space and time take on the poetry of both writers, investigating the possibility of those \"chronotopos\" be useful to the revelation of the human experience in the time and the space.

A partir da análise das relações espaciotemporais no poema O Sentimento dum Ocidental queremos demonstrar que a obra poética de Cesário Verde se constitui num incessante processo de fragmentação e busca de totalidade. Sua coesão mostra, de modo sintético, uma visão de mundo e constitui um sumário da problemática cesariana, não apenas dos poemas dessa fase ou ciclo específico, mas do conjunto de sua poesia. Essas duas funções, a coesão e a problemática, revelam a prevalência da unidade poética de Cesário, a despeito de sua aparente diversidade temática e originalidade de estilo o qual apresenta traços impressionistas. Consideradas as diferenças de contexto, o processo acima mencionado reflete a crise que vivemos nos dias atuais. Embora a crise contemporânea se apresente de modo diferente, podemos perceber algumas de suas raízes já expressas nos versos de Cesário, o que admite uma aproximação entre Literatura e Geografia.From the analysis of the space-time relations en the poem O Sentimento dum Ocidental we want to demonstrate that the poetic work of Cesário Verde is constructed by an incessant process of fragmentation and search for totality. Its cohesion shows, in a synthetic way, a world view and it constitutes a summary of the cesarian problematic, considering not only the poems of this phase or specific cycle, but the whole of his poetry. These two functions, cohesion and problematic, reveal the prevalence of the poetic unity of Cesário, despite its apparent thematic diversity and originality of style which presents some impressionist traces. Taking into consideration the differences of context, the process above mentioned reflects the crisis we live nowadays. Even though the contemporary crisis shows itself in a different manner, we can perceive some of its roots already expressed in Cesários verses, what admits an approaching between Literature and Geography

CAPES
A poesia visual coloca a visão como âmago do processo criativo, deslocando-se no tempo como um método voltado à forma estética da palavra. Afastada da simples ideia de lidar somente com a imagem, a poesia visual abarca características plásticas envolvendo o verbal e não verbal. A poesia ligada à visualidade irrompe o século XX e percorre o século XXI, em que a presença dos computadores impulsiona a experimentar novas modalidades. Nesse contexto, esta dissertação visa analisar, sob diferentes perspectivas semiológicas, a obra literária OLHLO2: Poesia Visual (2007), do poeta contemporâneo Luiz Augusto Knop de Mendonça – KNORR, a qual chama a atenção pelas rupturas estruturais do livro/jogo. Este se constitui de uma caixa pequena, em que a abertura lateral mostra cinquenta e quatro lâminas, cada qual com um poema independente. No verso das lâminas, legendas aparecem com o título, ano de produção e dizer explicativo. Apesar de uma demarcação temporal de execução, o marco principal do livro/jogo é uma desordem sequencial das lâminas poéticas. Pretende-se neste trabalho mostrar como a sintaxe tempo e espaço norteiam as escolhas pictóricas dos poemas selecionados, enquanto naipes do jogo de Knorr (2007). Assim, busca-se compreender como na obra o tempo está ligado ao aspecto não linear da língua caro ao jogo poético inerente à literatura. Do mesmo modo, objetiva-se entender como a noção de espaço, a partir da espacialidade da linguagem e do não verbal, implementa uma maneira de enxergar variados sentidos da experiência de estar no mundo e significar(-se). Bem como entender o curinga, como aquele que perpassa as noções de tempo e espaço. Vê-se o curinga como um conjunto de cartas que privilegia o uso das ambiguidades e a concomitâncias de sentidos interpretativos. Para realização de tais análises, serão escolhidas quarenta e oito poemas que, ao tematizarem sobre tempo, espaço e curinga revelam suas significações como jogo poético-visual.
Visual poetry puts vision at the core of the creative process, running through time as a method concerning the aesthetical shape of the word.Far from the oversimplifying idea of dealing only with image, visual poetry embraces features of the visual arts which connect the verbal and the non verbal. Poetry characterized by visual aspects bursts into the 20th century and goes through the 21st century, in which the presence of computers motivates experiences with new modalities. In this context, the present work aims at analyzing, under distinct semiological perspectives, the literary work "OLHLO2: Poesia Visual" (2007), by the contemporary poet Luiz Augusto Knop de Mendonça - KNORR, which captures attention due to the structural break within the book/game. OLHLO2 consists in a small box, where the side opening shows 54 cards, each of which contains a poem that is independent from the others. At the back of the cards, subtitles appear along with the title, year of production and a brief explanation. Despite of a temporal demarcation of execution, the main landmark of the book/game is the sequential disorder of the poetical cards, each card containing one single poem. This work intends to show how the syntax of time and space guide the pictorial choices of the selected poems as suits of the game by Knorr (2007). In this sense, the goal is to understand how, in OLHO2, time is connected to the nonlinear aspect of the language, so important to the poetical play inherent to literature. Similarly, the purpose is also to understand how the notion of space, through the spatiality of the verbal and of the non verbal, implements a way of seeing multiple meanings of the experience of being in the world and to betake oneself. Understanding the wild cards as those which run through the notions of time and space is also a goal. The wild cards are seen as the ensemble of cards that evidence the ambiguities and the concomitance of different interpretative meanings. The analysis is made through the choice of forty-eight poems that, by bringing about the themes of time, space and of wild cards, reveal their multiple meanings as a visualpoetic game.

Previous issue date: 2014-02-26Carlos Drummond de Andrade s poetic work prompts the theme of spyexpiating (espia-expiando, in the Portuguese original), a demonstration of poetic truth in and of itself, through a dialectic-aesthetic prism, with deductive method and reflections, amassing the metaphysical, philosophical and poetical processes wherein the very author is both theme and object, and his work is a true Drummondian anthropology. The main goal of this paper is an attempt at demonstrating that the poet s lyrical self is in an expiatory state, in suffering for having spied, contemplated the outside world, living in a state of unrest in time and space, which allows for the relief of this state of disenchantment, the return poetic memorialism to the beginning, Itabira, which has been remembered, since the first poem in 1930 published in the book Alguma Poesia (Some Poetry, in literal translation) , as a lovely place, metaphorically preserved, thus behaving as the prodigal son of Brazilian poetry. The contact with Drummondian poetry surprises and captivates those who seek it, not only for the aesthetic pleasure, but also for the acute reflection which takes readers and makes them participants in this existential drama, to free them through poetry so they can bask in transcendence, in metaphors. The object is the word embodied in the poem, the saving Word. This research is based on the reflections of thinkers and literary critics such as Michel Foucault, Octavio Paz, Gaston Bachelard, Gilberto Mendonça Teles, Affonso Romano de Sant Anna, among others. The focus on the struggle of the imprisoned soul, impotent before the reality that threatens it, but which reveals itself in the poem, making the latter a freeing, solidary weapon, enabling withdrawal into the sources of emotion, which is larger than the stage of suffering; into the magic, the charm of art and language, as the all-saving, purifying water that flows from the lyrical self. All of this is ultimately combined into the charisma of the poet.
O texto poético de Carlos Drummond de Andrade é revelador do tema espiaexpiando, demonstração da verdade poética por si mesma, num prisma dialéticoesteticista, com um método e reflexões dedutivas ao consubstanciar os procedimentos metafísicos, filosóficos, poéticos, nos quais o próprio autor é tema e objeto, e a sua obra, uma verdadeira antropologia drummoniana. O objetivo principal, neste trabalho é a tentativa de demonstrar que o eu lírico do poeta encontra-se em estado de expiação, sofrimento, por ter espiado, olhado o mundo exterior, vivendo um estado de desassossego, no tempo e no espaço, o que possibilitará como alívio desse estado de desencanto, o retorno - memorialismo poético ao ponto de partida, Itabira que desde o primeiro poema, publicado em 1930, no livro Alguma Poesia é retomada na lembrança como fonte de amabilidade preservada metaforicamente, comportando assim, como o filho pródigo da poesia brasileira. O contato com o texto poético drummondiano surpreende e prende quem o busca, não somente pelo prazer estético, mas pela aguda reflexão que toma o leitor e o faz partícipe desse drama existencial a se libertar na poesia, se alimentar da transcendência, das metáforas. O objeto é a palavra corporificada no poema, como verbo salvador. Toma-se como suporte para esta pesquisa, as reflexões de pensadores e críticos literários como Michel Foucault, Octavio Paz, Gaston Bachelard, Gilberto Mendonça Teles, Affonso Romano de Sant Anna, entre outros. Enfocar o embate da alma prisioneira, impotente diante da realidade que a ameaça, mas que se revela no poema, transformando-o em arma libertária, solidária, possibilitando o recolher-se para as fontes da emoção, que é maior que o estágio de sofrimento, para a magia, encantamento da arte e da linguagem que salva como água purificadora vinda do eu lírico, da transcendência metafórica para outra realidade povoada pelo reino das palavras que passa a ser o carisma do poeta.

Esta tese orienta-se por uma leitura da lírica drummondiana, através da qual sobressai a análise da relação afetivo cognitiva que o poeta estabelece com elementos (pessoas, espaços, instituições...) perdidos na nebulosa do tempo, evidenciando-se, sobretudo, a mediação da dimensão temporal como recurso dinamizador da relação poesia/espaço. No atrito com o tempo corrosivo, o poeta dedica-se a registrar as conquistas e as perdas da maturidade, enriquecendo sua obra com a expressão das tensões vividas pelo homem que, lúcido, caminha para a dissipação. Por um lado, essa inscrição da existência na série cronológica faz nascer a noção de que a temporalidade é, em si, cega e irreversível, visto a seqüência dos tempos não garantir um traçado evolucionista do inferior para o superior. Por outro lado, a maturidade sobrevinda faculta-lhe um gesto de resistência: o seu deslocamento em direção aos antepassados para compreender a conformação de sua consciência permite-lhe restabelecer laços afetivos, e, nesse processo, recriar lingüisticamente o seu passado. Uma parcela considerável de sua poesia memorialística traz um tom profundamente marcado pela dúvida, pela inquietude, pelo sentimento de culpa. Esse período de autoanálise mais dura faz sua poesia resvalar na mitificação da família e da Minas Gerais de sua infância, o que acaba por lançar sobre si próprio certa suspeição, marcada principalmente pelo motivo do desajuste familiar. A partir de Lição de coisas, já aos 60 anos de idade, e principalmente com Boitempo, observa-se na poesia de Drummond uma disposição biográfica sem a pungência ou a acrimônia que se percebem em outros versos nos quais o poeta trata de si mesmo ao longo de sua obra.

Pełny tekst źródłaStreszczenie:
Cette thèse propose une synthèse autour des différents rôles de la lumière et de l'obscurité dans les Argonautiques d'Apollonios de Rhodes. Ce sujet comporte une forte composante lexicale, qui fait l'objet d'une étude dans la première partie, où les vocabulaires de la lumière et de l'obscurité chez Apollonios sont comparés aux emplois homériques. Ce thème interroge également les catégories de l'espace et du temps dans la mesure où lumière et obscurité structurent la narration autant qu'elles la déstructurent et proposent un itinéraire placé à la croisée de la barbarie et de la civilisation, état d'entre-deux qui reflète bien les craintes de l'époque alexandrine. La dialectique de la lumière et de l'obscurité permet aussi de mettre en perspective la notion d'héroïsme placée au cœur de l'épopée : la brillance des armes homériques fait alors place à l'éclat de la séduction, arme principale de Jason dont la valeur se mesure surtout dans le domaine érotique. Ce transfert des valeurs traditionnelles de la lumière sur le plan masculin s'accompagne d'une affirmation des pouvoirs féminins en contexte nocturne. Une quatrième partie interroge enfin le statut littéraire des Argonautiques à l'aune de la dialectique entre lumière et obscurité : l'épopée au long cours dénigrée par Callimaque peut en effet être lue comme un recueil poétique de pièces autonomes et une galerie de tableaux correspondant aux canons de l'esthétique hellénistique. Le dieu Apollon, dieu de la lumière et de la poésie placé au centre de l'oeuvre d'Apollonios, se fait le porte-parole privilégié d'un auteur au nom si proche du sien et devient le destinataire d'une sorte d'hymne atomisé qui mêle célébration poétique et réflexions métapoétiquesThrough this thesis, we aim to prove the various roles played by light and darkness in Apollonius Rhodius'Argonautica. In the first part, a lexical study specifically explores the terms expressing the ideas of light and darkness, in comparison to the Homeric references. Our thematic also tackles the issue of the construction of space and time, a notorious one in the Hellenistic period. The epic's structure is indeed based on the light and darkness' duality, but the threat of darkness symbolizing chaos is never far from the Argonauts who constantly struggle with barbarians and on the contrary symbolize Greek enlightment and civilization. The light and darkness'couple also allows us to give a new perspective on heroism, which is a central issue in Apollonius'poem. Whereas Homeric warriors project martial light due to their armour's glistening, Jason appears as love-hero shining with his purple cloak, an Hellenistic artefact replacing Achilles'shield described in the Iliad. At the same time, we can observe a kind of empowerment on the feminine side during the scenes occuring at night. In the fourth and last part, light and darkness endorse a metapoetical value, as they build a new kind of epic, like a collection of brief literary pieces joined together by a common celebration of Apollo, god of both poetry and light. Apollonius'Argonautica can therefore be seen as a prefiguration of Philostratus'Imagines, as it is built around a succession of vivid poetical paintings

Places are deeply specific, and often richly resonant for us in terms of memory, emotion, and association, yet we nevertheless frequently move through them insensible of their constitution and diversity, or the shaping influences they have upon our lives. As such, place affords a vital window into the creation and experience of poetry where the poet is herself attuned to the presence and effect of places; the challenge for the scholar is to articulate place's nature and role with respect that poetry.

Ce travail suit un objectif : montrer et démontrer le fait que dans le dit du texte tout n’est pas dit. Le voyage du personnage sur trois continents et la structure propre à l’écriture romanesque d’ordre épisodique contribuent à la distorsion de l’hégémonie d’un seul discours. A ceci, il faut ajouter la fragmentation de l’espace qui, comme procédé à la fois esthétique et stratégique, permet au romancier d’échapper à l’emprise discursive d’une idéologie qui se veut ubiquitaire. Ce travail envisage le narrateur, non comme une altérité constituée, mais comme une figure composite faite des pensées hétéroclites du romancier. Elle recèle une grande réserve de contradictions. Nous tentons de reconnaître dans le texte les intermittences du dire et du silence : des éléments hétérogènes qui se déploient sur une grille de nuances entre l’aliénation, le dégoût et la poésie.De la même manière que l’espace vacille entre la poésie et le monde prosaïque, les pôles sémantiques du texte, esthétiques et idéologiques, changent de frontières. Des unités sémantiques se transforment en des altérités glissantes qui tendent à échapper au procédé de conceptualisation. À la différence de toute approche critique idéaliste qui prétend à atteindre le sens absolu de l’objet en essayant de fusionner l’œuvre et la vie, nous montrons comment le sens esthétique suit son chemin de crête, demeure funambulesque. Nous abordons le concept de l’hétérogénéité non comme un concept purement esthétique qui caractérise la trame de l’écriture célinienne, mais comme un esprit sous-jacent à l’univers intellectuel de l’auteur. Par le recours aux divers procédés, le style de Céline illustre le vacillement de l’agencement sémantique entre l’aliénation et la libération, entre l’engagement et le désengagement, entre l’affirmation et le dénigrementThis work follows an objective: to show and to demonstrate the fact that in the said of the text everything is not said. The journey of the character on three continents and the structure of episodic novel writing contribute to the distortion of the hegemony of a single discourse. To this must be added the fragmentation of space which, as a process both aesthetic and strategic, allows the novelist to escape from the discursive grasp of an ideology that claims to be ubiquitous. This work envisages the narrator, not as a constituted otherness, but as a composite figure made up of the heterogeneous thoughts of the novelist. This figure contains a great reserve of contradictions. We try to recognize in the text the intermittencies of saying and of silence: heterogeneous elements which unfold on a grid of nuances between alienation, disgust and poetry.In the same way that space vacillates between poetry and the prosaic world, the semantic poles of the text, aesthetic and ideological, change borders. Semantic units are transformed into slippery alterity that tend to escape from the process of conceptualization. Unlike any idealistic critical approach which claims to reach the absolute meaning of the object by trying to merge work and life, we show how the aesthetic sense follows its crest path. We approach the concept of heterogeneity not as a purely aesthetic concept that characterizes the framework of Celine's writing but as a spirit underlying the Celinian intellectual universe. Through the use of various methods, Céline's style illustrates the semantic vacillation between alienation and liberation, between commitment and disengagement, between affirmation and denigration

Pełny tekst źródłaStreszczenie:
La connaissance du monde intérieur est réalisée dans la philosophie de Bergson par le moyen de l’intuition, et les Surréalistes réalisent par le voyage de l’imaginaire la découverte des réalités au-delà de ce monde du réel. Dans le cas de Bergson la réalisation principale est la durée, et chez les surréalistes l’effondrement de la raison et le déplacement des limites habituelles du temps et de l’espace sont la conséquence de leur effort de création poétique. Poursuivant son raisonnement philosophique Bergson révèle la forme mouvante de la durée, c’est-à-dire la courbe, mouvement fondé sur la grâce et la dissolution des trois temps. C’est alors que la créativité artistique et poétique du surréalisme se révèle proche de la pensée bergsonienne, et l’analyse de Julien Gracq en vertu de laquelle les Surréalistes sont plus proches de Bergson que de Freud prendra tout son sens.La présente recherche s’efforcera donc de mettre en évidence cette proximité entre le surréalisme et la pensée bergsonienne en recherchant la présence de la durée (telle que définie par Bergson) et de ses qualités spatiales et temporelles, c’est-à-dire la continuité dans le temps et la simultanéité, dans l’art surréaliste. Cette recherche intitulée « L’Esthétique de la courbe dans la poésie surréaliste » vise à révéler la forte présence de la notion de la courbe et de ses caractéristiques formelles et internes comme la fluidité, la grâce, le caractère serpentin et cyclique, dans la poésie et l’art de ce mouvement artistique contemporainIn Bergson’s school of thought the knowledge of the inside world is achieved through intuition, and in the Surrealism artistic movement it’s through the “voyage of imagination” that one achieves the discovery of the reality beyond this world. The former reaches the concept of “duration”, while the result of the latter’s poetic efforts is the dissolution of logic and the moving of the boundaries of time and space. In his philosophical musings, Bergson discovers the true form of the “duration” which is the curved line, a movement based on grace and the union of the three tenses. At the same time, the surrealist artists will reach through their poetic and artistic creation something that is very similar to Bergson’s philosophy. It is then that Julien Gracq’s analysis about surrealism being closer to Bergson than to Freud becomes meaningful to us.That being in consideration, the aim of this work will be to reveal the close proximity between the surrealist artists and Bergson, and doing so identify the place of the bergsonian “duration” and its spatio-temporal qualities, namely “continuity in time” and “simultaneity”, in surrealist art. This research, entitled “Esthetics of the curve in surrealist poetry” aims to bring the evidence of the presence of the concept of the curve and its formal and internal qualities like fluidity, graciousness and the serpentine and cyclic qualities, in the art and poetry of the surrealism

The phenomenon of fading constitutes a fundamental problem in wireless communications. Researchers have proposed many methods to improve the reliability of communication over wireless channels in the presence of fading. Many studies on this topic have focused on diversity techniques. Transmit diversity is a common diversity type in which multiple antennas are employed at the transmitter. Space-time coding is a technique based on transmit diversity introduced by Tarokh et alii in 1998.
In this thesis, various types of space-time codes are examined. Since they were originally introduced in the form of trellis codes, a major part is devoted to space-time trellis codes where the fundamental design criteria are established. Then, space-time block coding, which presents a different approach, is introduced and orthogonal spacetime block codes are analyzed in some detail. Lastly, rank codes from coding theory
are studied and their relation to space-time coding are investigated.

This thesis considers the ways in which poets writing in English in Bombay have represented the city and negotiated its particular challenges, focusing in particular on poets starting to publish during the 1950s and 1960s. Examining in detail work by poets whom Bruce King refers to as constituting a “Bombay circle”, this project examines how Nissim Ezekiel, Adil Jussawalla, Gieve Patel and Arun Kolatkar in particular have represented the modernity of the city (Modern Indian Poetry in English 45). Despite Bombay’s significance in postcolonial studies, this highly mediated city has been disassociated from its material histories by recent critical and imaginative portrayals. The over-determination of Bombay is countered and nuanced, this thesis suggests, by examining the ways in which poets have represented the city. Evaluating Bombay poetry closely, and considering the relationship between poetic form and language and the articulation of space, this project asks how poetry written in the city contributes to, intervenes in or disarticulates dominant readings of Bombay. The material contexts in which poetry was written and circulated provide further significant and under-researched sites of engagement with this postcolonial city. This thesis thus turns to a period in the city’s cultural and literary history that has not been extensively documented: to the emergence of its poetry scene from the 1950s onwards. This project combines close, poetic analyses with archival research, examining Bombay’s little magazines and small press publishers, and tracing the various local and international affiliations evidenced in this body of work. In doing so, its aim is to historicize and contextualize the city and the work of its poets, enriching a critical and materialist understanding of this paradigmatic city.

In this thesis we investigate the effects of the physical
constraints such as antenna aperture size, antenna geometry and
non-isotropic scattering distribution parameters (angle of
arrival/departure and angular spread) on the performance of coherent
and non-coherent space-time coded wireless communication systems.
First, we derive analytical expressions for the exact pairwise error
probability (PEP) and PEP upper-bound of coherent and non-coherent
space-time coded systems operating over spatially correlated fading
channels using a moment-generating function-based approach. These
analytical expressions account for antenna spacing, antenna
geometries and scattering distribution models. Using these new PEP
expressions, the degree of the effect of antenna spacing, antenna
geometry and angular spread is quantified on the diversity advantage
(robustness) given by a space-time code. It is shown that the number
of antennas that can be employed in a fixed antenna aperture without
diminishing the diversity advantage of a space-time code is
determined by the size of the antenna aperture, antenna geometry and
the richness of the scattering environment.
¶
In realistic channel environments the performance of space-time
coded multiple-input multiple output (MIMO) systems is significantly
reduced due to non-ideal antenna placement and non-isotropic
scattering. In this thesis, by exploiting the spatial dimension of a
MIMO channel we introduce the novel use of linear spatial precoding
(or power-loading) based on fixed and known parameters of MIMO
channels to ameliorate the effects of non-ideal antenna placement on
the performance of coherent and non-coherent space-time codes. The
spatial precoder virtually arranges the antennas into an optimal
configuration so that the spatial correlation between all antenna
elements is minimum. With this design, the precoder is fixed for
fixed antenna placement and the transmitter does not require any
feedback of channel state information (partial or full) from the
receiver. We also derive precoding schemes to exploit non-isotropic
scattering distribution parameters of the scattering channel to
improve the performance of space-time codes applied on MIMO systems
in non-isotropic scattering environments. However, these schemes
require the receiver to estimate the non-isotropic parameters and
feed them back to the transmitter.
¶
The idea of precoding based on fixed parameters of MIMO channels is
extended to maximize the capacity of spatially constrained dense
antenna arrays. It is shown that the theoretical maximum capacity
available from a fixed region of space can be achieved by power
loading based on previously unutilized channel state information
contained in the antenna locations. We analyzed the correlation
between different modal orders generated at the transmitter region
due to spatially constrained antenna arrays in non-isotropic
scattering environments, and showed that adjacent modes contribute
to higher correlation at the transmitter region. Based on this
result, a power loading scheme is proposed which reduces the effects
of correlation between adjacent modes at the transmitter region by
nulling power onto adjacent transmit modes.
¶
Furthermore, in this thesis a general space-time channel model for
down-link transmission in a mobile multiple antenna communication
system is developed. The model incorporates deterministic
quantities such as physical antenna positions and the motion of the
mobile unit (velocity and the direction), and random quantities to
capture random scattering environment modeled using a bi-angular
power distribution and, in the simplest case, the covariance between
transmit and receive angles which captures statistical
interdependency. The Kronecker model is shown to be a special case
when the power distribution is separable and is shown to
overestimate MIMO system performance whenever there is more than one
scattering cluster. Expressions for space-time cross correlations
and space-frequency cross spectra are given for a number of
scattering distributions using Gaussian and Morgenstern's family of
multivariate distributions. These new expressions extend the
classical Jake's and Clarke's correlation models to general
non-isotropic scattering environments.

While the political and social spaces of Old English literature are fairly well understood, this project examines the conceptual spaces in Old English poetry. The Anglo-Saxons possessed a richly metaphorical understanding of the world, not merely in the sense of artistically ornamental metaphor, but in Lakoff and Johnson's sense of conceptual metaphor, which reflects the structures of thought through which a culture understands their world. Three domains exhibit developed systems of conceptual metaphor for the Anglo-Saxons: the self, death, and the world. First, the Anglo-Saxon self is composed of four distinct entities--body, mind, soul, and a life-force--which each behave independently as they compete for control in poems like The Wanderer, The Seafarer, and Soul and Body. Second, death for the Anglo-Saxon is expressed through a number of metaphors involving the status or placement of the body: removal to a distant place; separation of the body and the soul; location down on or within the earth; and the loss of life as a possession. Predominance of a particular metaphor contributes to the effects of individual poems, from The Fates of the Apostles and Beowulf to The Battle of Maldon and The Wife's Lament. Third, the Anglo-Saxon world is a large structure like a building, with its three primary components--heaven, hell, and earth--each themselves presented as building-like structures. Old English poetry, including native versions of Genesis, reveal heaven to be a protective Anglo-Saxon hall, while hell is a cold prison. The earth, in poems like Christ II and Guthlac B, is either a wide plain or a comforting house. Christ I connects these worlds through gates, including Mary, characterized as a wall-door. Finally, the apocalyptic Christ III employs metaphorical spaces for all three conceptual domains treated in this study but dramatizes their breakdown even as it reveals spatial enclosure the overarching structure of metaphorical concepts in Old English poetry.

In Romantic studies, Romanticism is regarded as a reaction against modernity, or more accurately, a self-critique of modernity. There have been critical debates over the nature of the preoccupation of the Romantics with the past and the natural world, whether such concern is an illustration of the reactionary tendency of Romanticism, or an aesthetic innovation of the Romantics. This study tries to approach this problem from the perspective of space. It draws from the spatial theory of Henri Lefebvre, discussed in the Production of Space, in which Lefebvre conceives a spatial history of modernity, and sees Romanticism as the cultural movement that took place at the threshold of the formation of abstract space. The poetry of three British Romantic writers, William Wordsworth, S. T. Coleridge and Joanna Baillie, is examined. This study analyses how the writers’ thinking and poetry writing are interactive with the formation of social space during the Romantic period. Their poetry embodies the lived experience of the time. The writers show an awareness of the performative aspect of poetry, that poetry is a kind of linguistic creation instead of mere representation, which can be used to appropriate the lived space of reality. This awareness is particular to these Romantic writers because their poetic tactics are socially contextualized. Poetry is their method, as well as manner of life, for confronting the unprecedented social changes brought by modernity. By using Merleau-Ponty’s phenomenology, an examination of the significance of the body and perception in Romantic poetry is also employed to show how, through the use of performative poetic language, the writers re-create their lived space so as to counter the dominance of abstract space.

Thesis (M. Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 1988.Includes bibliographical references (leaves 156-159).
This thesis describes the development of new concepts in acoustical analysis from their inception to implementation as a computer design tool. Research is focused on a computer program which aids the designer to visually conceive the interactions of acoustics within a geometrical~y defined environment by synthesizing the propagation of sound in a three dimensional space over time. Information is communicated through a unique use of images that are better suited for interfacing with the design process. The first part of this thesis describes the concepts behind the development of a graphic acoustical rendering program to a working level. This involves the development of a computer ray tracing prototype that is sufficiently powerful to explore the issues facing this new design and analysis methodology. The second part uses this program to evaluate existing performance spaces in order to establish qualitative criteria in a new visual format. Representational issues relating to the visual perception of acoustic spaces are also explored. In the third part, the program is integrated into the design process. I apply this acoustical tool to an actual design situation by remodeling a large performance hall in Medford, Massachusetts. Chevalier Auditorium is a real project, commissioned by the city of Medford, whose program requirements closely match my intentions in scope, scale and nature of a design for exploring this new acoustical analysis and design methodology. Finally, I summarize this program's effectiveness and discuss its potential in more sophisticated future design environments.

This collection of work contains poems that are attempting to reach a sense of understanding about the past in regard to place, landscape, architecture, and memory in relation to the self--the speaker, the self-imposed I. The perception of memory, and in particular the prevalence of false memories surrounding place and person are of major concern in this collection, along with the historical and personal narratives moving out of a voice rooted in the Mojave Desert, and in particular, Las Vegas, Nevada. These poems are working through the speaker’s complicated relationship with the desert, and the erosion of place, of home. These poems are an effort to recognize what it means to learn from the desert, to learn from Las Vegas.

This thesis investigates exchanges between poetry and criticism through the work of contemporary writers who seek to interrogate the boundaries between these discourses. Rather than conventional poetics or manifestos these poets are producing poetry that actively explores the tenets of their critical thinking, using hybrid forms to challenge perceived boundaries between practice and theory, art and criticism. In rethinking the nature and function of poetry while challenging critical conventions, this work has implications for both modes of writing. Itself a hybrid of poetry and theory, a fusion of critical and creative writing, the thesis enacts a performative investigation of this scene of writing.

Pełny tekst źródłaStreszczenie:
This thesis investigates the manner in which an understanding of the spatial nature of the contemporary lyric poem (broadly reducible to the poem as and the poem of space) combines with voicing and affect in the act of reading poetry to create a third way in which space operates in the lyric: the ‘vocalic space’ of the voiced lyric poem. Together with the poem as and of space, the vocalic space of the contemporary lyric poem gives way to an enunciating I and eye with which we, as reader, identify and which we voice, in a process of ‘affective mapping’. Voice, and the spaces the I/eye of the contemporary lyric poem visualises and articulates, is affective, contested, and multiple. Visual and vocalic identification with the voice of the poem through this free, fragmented, or multiple, I/eye leads us to understand more fully the poem on its own terms. The chapters of this thesis offer readings of John Montague’s The Rough Field, Thomas Kinsella’s A Technical Supplement, Kathleen Jamie’s This Weird Estate, and Alice Oswald’s Dart, as well as the poetry of Seamus Heaney, Thom Gunn and Mimi Khalvati, in order to investigate the implication of this thesis on the way we read, voice, and analyse contemporary British lyric poetry. The work of each poet offers different perspectives on perception, place, and space, and different engagements with the voiced and textual spaces of poetry, from the more formal poetics of Heaney, Jamie, and Gunn, to the experiments with text and image of Montague, Kinsella, and Jamie, the use of different languages by Montague, Jamie, and Khalvati, and the manipulation of the space of the page and angle of poetic vision and voice by Montague, Khalvati, and Oswald. The chapters work almost chronologically from The Rough Field (1972) to Dart (2002) with an emphasis on the importance of space, voice, and affect to the readings of the poems and poets in question.

All animals are adapted to the environmental conditions of the habitat they chose to live in. It was the aim of this PhD-project, to show which behavioral strategies are expressed as mechanisms to cope with the constraints, which contribute to the natural selection pressure acting on individuals. For this purpose, small mammals were exposed to different levels and types of predation risk while actively foraging. Individuals were either exposed to different predator types (airborne or ground) or combinations of both, or to indirect predators (nest predators). Risk was assumed to be distributed homogeneously, so changing the habitat or temporal adaptations where not regarded as potential options. Results show that wild-caught voles have strategic answers to this homogeneously distributed risk, which is perceived by tactile, olfactory or acoustic cues. Thus, they do not have to know an absolut quality (e.g., in terms of food provisioning and risk levels of all possible habitats), but they can adapt their behavior to the actual circumstances. Deriving risk uniform levels from cues and adjusting activity levels to the perceived risk is an option to deal with predators of the same size or with unforeseeable attack rates. Experiments showed that as long as there are no safe places or times, it is best to reduce activity and behave as inconspicuous as possible as long as the costs of missed opportunities do not exceed the benefits of a higher survival probability. Test showed that these costs apparently grow faster for males than for females, especially in times of inactivity. This is supported by strong predatory pressure on the most active groups of rodents (young males, sexually active or dispersers) leading to extremely female-biased operative sex ratios in natural populations.
Other groups of animals, those with parental duties such as nest guarding, for example, have to deal with the actual risk in their habitat as well. Strategies to indirect predation pressure were tested by using bank vole mothers, confronted with a nest predator that posed no actual threat to themselves but to their young (Sorex araneus). They reduced travelling and concentrated their effort in the presence of shrews, independent of the different nutritional provisioning of food by varying resource levels due to the different seasons. Additionally, they exhibited nest-guarding strategies by not foraging in the vicinity of the nest site in order to reduce conspicuous scent marks. The repetition of the experiment in summer and autumn showed that changing environmental constraints can have a severe impact on results of outdoor studies. In our case, changing resource levels changed the type of interaction between the two species.
The experiments show that it is important to analyze decision making and optimality models on an individual level, and, when that is not possible (maybe because of the constraints of field work), groups of animals should be classified by using the least common denominator that can be identified (such as sex, age, origin or kinship). This will control for the effects of the sex or stage of life history or the individual´s reproductive and nutritional status on decision making and will narrow the wide behavioral variability associated with the complex term of optimality.Das Verhalten von Tieren ist das Ergebnis eines kontinuierlichen Anpassungsprozesses im Laufe der Evolution einer Art und damit der Veränderung der Umgebung in der es lebt und der Interaktion mit anderen Arten. Dies wird besonders deutlich im Verhalten von potentiellen Beutetieren, ihre Strategien beinhalten meist ein möglichst unauffälliges Verhalten im Zusammenspiel mit reduzierter Bewegung und möglichst guter Tarnung. Dementgegen stehen essentielle Bedürfnisse, wie zum Beispiel die Nahrungssuche, die Verteidigung von Ressourcen (zum Beispiel Territorien, Futterstellen) und die Suche nach Paarungspartnern. Beutetiere leben also in einem Spannungsfeld indem sie Ihr Verhalten optimieren müssen. Hierbei stehen die Ernährung, erfolgreiche Verpaarung und andere Chancen auf der einen Seite, die Vermeidung von Begegnungen mit Prädatoren auf der anderen. Vor allem Kleinsäuger sind häufig als Beutetiere mit einer Vielzahl von Prädatoren aus der Luft und auf dem Boden konfrontiert. Sie müssen für die verschiedenen Bedrohungen adaptive Verhaltensanpassungen bereit haben und in der Lage sein, auf die optischen, olfaktorischen oder akustischen Signale, die die Gefahr durch Prädatoren anzeigen, mit plastischen Verhaltensmustern zu reagieren. Die vorliegende Dissertation beschäftigt sich mit bisher als Konstanten behandelten Faktoren und untersucht anhand von Verhaltensexperimenten mit wilden Wühlmäusen (Microtus arvalis) folgende Fragestellungen: - Wie verhalten sich Tiere, die einer homogenen Risikoverteilung ausgesetzt sind, zum Beispiel weil ihr Prädator genauso gross ist wie sie, im gleichen Habitat lebt und es keinen sicheren Ort gibt? - Mit welchen Anpassungen reagieren Tiere, wenn sie gleichzeitig verschiedenen Prädatoren ausgesetzt sind? - Wie unterscheiden sich die Nahrungssuchstrategien von Männchen und Weibchen? - Wie verhalten sich laktierende Weibchen, die einer permanenten, indirekten Gefahr, z.B. durch einen Nestprädator ausgesetzt sind? Die Ergebnisse der verschiedenen Versuche in künstlichen Arenen und Aussengehegen zeigen, dass die Mäuse in der Lage sind, adaptive Verhaltensanpassung an homogenes Risiko und verschiedene Prädationstypen abzurufen. So sind sie in der Lage, Luft- von Bodenprädatoren zu unterscheiden und jeweils das Verhalten zu zeigen, dass die größtmögliche Sicherheit mit sich bringt. Die simultane Kombination von verschiedenen Prädatoren bewirkt hierbei additive Effekte. Gibt es keine Auswahl zwischen Habitaten, sondern nur unterschiedliche homogene Risikolevel, reagieren sie auf steigendes Risiko immer mit verminderter Aktivität und konzentrieren ihre Nahrungssuche auf weniger Futterstellen, beuten diese dafür jedoch länger aus. Die Wertigkeit von Futterstellen und alternativen Optionen verändert sich also mit dem Risikolevel. Ähnliches zeigt sich auch in den unterschiedlichen Futtersuchstrategien von Männchen und Weibchen. Die untersuchte Art ist polygyn und multivoltin, dementsprechend verbinden die Männchen mit ihrer Nahrungssuche Aktivitäten wie die Suche nach Paarungspartnern und unterscheiden sich die Aktivitätsmuster zwischen Männchen und Weibchen. Zusätzlich zeigen die Ergebnisse, das laktierende Weibchen in der Lage sind, das Risiko für sich und für Ihre Jungen abzuschätzen, wenn sie mit einem Nestprädator (Sorex araneus) konfrontiert werden. Für die Interaktion zwischen diesen beiden Arten ist jedoch die Saison (und damit die Ressourcenlage), in der sie sich begegnen, von entscheidender Bedeutung. Wühlmäuse reagieren mit entsprechenden Verhaltensanpassungen zum Schutz des Nestes um die Überlebenschancen ihrer letzten Würfe im Herbst zu erhöhen. Die vorliegende Arbeit konnte grundsätzliche Probleme der antiprädatorischen Verhaltensanpassung von Beutetieren klären und wichtige Faktoren der Entscheidungsfindung unter Prädationsdruck analysieren. Sie zeigt, dass Tiere das Risiko in ihrer Umgebung nicht unbedingt über direkt Signale wahrnehmen, sondern ihre Verhaltensstrategien einem empfundenen Gesamtrisikolevel anpassen. Dies ermöglicht ihnen, adaptive Strategien zu verfolgen, auch wenn sie keine Auswahl an sicheren Habitaten haben. Sie zeigt auch die unterschiedliche Wahrnehmung von Risiken durch Männchen und Weibchen, die durch die unterschiedlichen mit der Aktivität zusätzlich wahrgenommenen Chancen verknüpft zu sein scheint. Zusätzlich wurde der Einfluss des reproduktiven Status (z.B. laktierend), sowie der Ressourcenlage (z. B. je nach Saison) nachgewiesen.

The combination of Space-Time (ST) coding and Continuous-Phase Modulation (CPM) produces a low power, energy efficient communication scheme suitable for wireless transmission. Space-time coding increases the reliability of transmission, and continuous-phase modulation (CPM) has the
potential to provide considerable energy savings. CPM is a modulation technique that involves the transmission of a signal with continuous-phase and a constant envelope, where the continuous-phase property produces a very bandwidth efficient signal, and the constant-envelope property enables non
linear (and thus energy efficient) signal amplification. The ST-CPM code is of special interest for wireless sensors because in the wireless sensor network environment energy consumption is highly constrained. The combination of ST codes and CPM is non-trivial and thus ST-CPM codes based upon
block-based orthogonal and diagonal signal matrices are presented. These codes are forms the basis of a distributed ST-CPM code. The distributed ST codes are designed to operate in wireless networks containing a large set of nodes, of which only a small a priori unknown subset will be active at any
time. The devised distributed ST-CPM scheme combines the ST-CPM code with a diagonal signaling matrix, (commonly assigned to all relay nodes) with signature vectors(uniquely assigned to nodes). The energy consumption of the proposed distributed ST-CPM scheme is compared with that of a distributed ST linear modulation (LM) scheme. The distributed ST-CPM scheme is shown to
outperform the distributed ST-LM scheme for all but short-range transmission. Finally, a serially concatenated code for ST-CPM is proposed. The concatenated code consists of the diagonal signalling matrix as the inner code, and a class of double parity check (DPC) codes as the outer code. The
resulting concatenated codes that are formed from the ST-CPM code and a DPC code are shown to provide performance close to capacity, and to provide performance superior to that provided by the more common combination of CPM, or ST-CPM schemes with convolutional codes.

We present a novel algorithm for space-time reconstruction of deforming meshes. Based on partial meshes at every frame, and sparse optical flow information between frames, we reconstruct a globally consistent, crossparameterized, and hole filled sequence of meshes. Our method is based on pair-wise merging of frame sequences while correcting for changes in topology, filling in missing geometry, and repairing inconsistencies. We also introduce a robust method for filling in missing geometry in each frame of the sequence using geometry from another frame. Using this method we can propagate geometry over the full frame sequence, correcting errors and filling in holes even in regions of the object that are not observed in the input meshes for extended periods of time. Unlike other approaches, our method does not require template geometry, nor is it limited to narrow classes of objects or purely isometric deformations.

This work utilizes a spatial theory approach to meditate on postwar Japanese society and cinema. It is not a history of Japanese postwar cinema, or a survey of notable directors and genres. Rather, the focus is specifically on film and its relation to the deeper tropes of Japanese society; in particular, on how the sense of nation is affirmed and/or challenged within a postwar period of remarkable change. Understanding such a structure greatly aids in analyzing the forms and meanings within the films. The question of National Cinema, then, is approached by exploring how the interaction of spatial-temporal elements affect both the social construction and filmic practices of the nation.The first part of the dissertation features an extended analysis of Japanese society using a variety of historical, philosophical and theoretical sources, both Japanese and foreign. They provide a theoretical base and a social history that ground the critical readings of the selected films; all of which are well-known and widely available. Part two is a close textual analysis of five 1950s productions---from a range of films and genres---that are contrasted with three films from the late 1980s/early 1990s. The final chapter examines notions about National Cinema in light of the preceding film analysis.

This thesis is concerned with an investigation of twistorial structures present in curved Lorentzian space-times. Chapter 1 introduces the basic definitions and some theorems that will be used later in the text. Chapter 2 investigates generalised connections that arise in twister theory. First the Cartan con-formal connection is studied, and some of the geometry underlying it is shown to be that used by Fefferman and Graham C133. Also a condition that a space-time is conformal to vacuum is given. Secondly the theory of the Chern connection associated to a C.R. manifold is developed in such a way as to make the calculation of the connection associated to a twistor C.R. manifold straight forward. A new proof of the Chern theorem of existence and uniqueness is given. The Chern connection of a twistor C.R. manifold is then calculated, and discussed. In particular S-dimensionai C.R. manifolds arising as twistor C.R. manifolds are characterised. Canonical structures peculiar to the twister case are discussed. Applications of C.R. manifold theory to algebraically special space-times are suggested. Chapter three analyses how various twistorial structures behave in linearised general relativity. First, deformations of the space of complex null geodesies corresponding to variations of the conformal structure of space-time are shown to be generated by hami1tonians. Those that correspond to variations in the metric satisfying the field equations are given, along with hamiltonians corresponding to different fields and field equations. Beneralisations to nonlinear equations are discussed. These ideas are applied to hypersurface twisters in linearised theory, using fiat hypersurfaces and Cech cohoeology. Expressions are obtained for the deformation of the complex structure of the spaces and their evolution. The results are generalised to non flat hypersurfaces using Dolbeault cohomolcgy. It is shown that certain canonically defined forms on the spin bundle are preferred Dolbeault representatives for derivatives of the twister cohomology classes corresponding to the linearised field. In chapter four I generalise the results of chapter three to curved space using the Chern connection. In particular twistorial formulations of the constraint equations are given, and a formula for the evolution that satisfies the the vacuum evolution equations is given in terms of an "infinity" twistor and a "time" twister. This is then discussed. In chapter five I make some comments on the interpretation of a three form on the spin bundle discovered by B.A.J. Sparling as the gravitational hami1tonian. I then use this to show that one can give an interpretation of Penrose's quasi-local angular momentum twistor in terms of the canonical formalism.

Dans ma thèse, je décris les feuilles stables et instables pour le flot géodésique sur l’espace des géodésiques non-errant de type espace d’un espace-temps de Margulis et je démontre des propriétés de contraction des feuilles sous le flot. Je montre aussi que la monodromie d’un espace-temps de Margulis est une représentation Anosov dans un groupe de Lie non semisimple. En outre, je montre que les applications limites et reparamétrisation varient analytiquement. Enfin, à l’aide de la propriété métrique Anosov, nous définissons la métrique de pression sur l’espace modulaire des espaces-temps de Margulis sans pointes et je démontre qu’elle est définie positive sur les sections d’entropie constanteIn my thesis I describe the stable and unstable leaves for the geodesic flow on the space of non-wandering spacelike geodesics of a Margulis Space Time and prove contraction properties of the leaves under the flow. I also show that monodromy of Margulis Space Times are “Anosov representations in non semi-simple Lie groups”. Moreover, I show that the limit maps and reparametrizations vary analytically. Finally using the metric Ansosov property we define the Pressure metric on the Moduli Space of Margulis Space Times without “cusps” and show that it is positive definite on the constant entropy sections

Les biologistes moléculaires cherchent à comprendre comment fonctionnent les organismes au niveau moléculaire. Le but ultime de ces recherches est d’offrir la possibilité de manipuler sans risque des cellules et/ou des organismes afin de combattre des maladies génétiques, d’éradiquer les maladies contagieuses ou par exemple d’améliorer les qualités nutritives de l’alimentation. Actuellement, la manière la plus précise et pratique de comprendre le fonctionnement d’un organisme est d’étudier son transcriptome et ses variations dans l’espace et le temps. Suivant cette logique, le but de ma thèse de doctorat a été double: (1) estimer l’importance de l’épissage alternatif qui engendre une diversité des transcripts (2) étudier les transcriptomes de deux organismes modèles : Mus musculus et Drosophila melanogaster, respectivement dans l’espace et le temps. Durant ces années de recherche, j’ai rassemblé des découvertes intéressantes concernant l’expression des gènes et sa régulation. D’abord, l’épissage alternatif s’est avéré être un méchanisme important non seulement en terme de fréquence (des transcripts alternatifs sont générés pour une vaste majorité des gènes, et ce dans de multiples espèces), mais aussi en terme d’évolution (l’épissage alternatif semble permettre à un gène d’évoluer sans conséquences trop négatives pour l’organisme). Par ailleurs nous avons prouvé que le niveau d’expression de transcripts n’est pas en soi synonyme de fonction: il y a en effet une quantité non négligeable d’expression neutre, qui doit être prise en compte lors de l’assignation d’une fonction à un gène, uniquement basée sur la similarité de son profil d’expression par rapport à celui d’un gène de fonction connue. Enfin, nous avons étudié des séries de puces à ADN appliquées à l’embryogenèse de la mouche dans le temps, en utilisant une technique non conventionnelle pour ce type d’approche. Nous avons réparti les gènes en différentes classes selon leurs profils d’expression. Nous avons pu prouver que ces classes de gènes ont des critères biologiques en commun, ce qui laisse supposer que les gènes inconnus ou mal caractérisés qui tombent dans ces classes sont d’interessants points de départ pour de futures recherches. Des découvertes inestimables ont été et seront encore faites en biologie moléculaire grâce à l’étude des transcriptomes dans des organismes variés, analysés dans différentes conditions. Cependant, il est devenu clair qu’à cause de la présence de nombreuses étapes de régulation après la transcription, dont l’épissage alternatif, seule l’analyse des protéomes permettra d’obtenir une vision complète de la biologie de la cellule.

In architecture there is perhaps no better opportunity to capture movement and change than in the design of thresholds. They can be a simple strip of metal beneath a doorway, barely noticed as you pass over it, or a grand atrium that you stop and marvel at on your way into the office. They can manifest as a change of materials or finishes, or of some parameter such as ceiling height. They might even be immaterial altogether, like the boundary between light and shadow.
Thresholds transcend the physical to effect a psychological experience. They can be spatial or temporal or some combination of the two, but whatever form they take, all thresholds can be said to be mediators of our movement from one spatial status to another. Inside to outside, public to private, here to there. Too often our buildings relegate these changes to doors or openings that have little connection to the buildings they are a part of, and so our awareness of passage from space to space is diminished. This thesis explores ways to enrich the architecture of the threshold so that it doesn't merely recede to the bounds of our perception.Master of Architecture
The term "threshold" often brings to mind a strip of material at the base of a doorway, but architecture considers thresholds more broadly as moments of movement or change. This thesis examines such moments in an original building design, proposing several threshold types and exploring their impact on occupants.

ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, CaliforniaThis paper describes the use of orthogonal space-time block codes to overcome the performance and complexity difficulties associated with the use of Shaped Offset QPSK (SOQPSK) modulation, a ternary continuous phase modulation (CPM), in multiple-input multiple-output telemetry systems. The orthogonal space-time block code is applied to SOQPSK waveforms in the same way it would be applied to symbols. The procedure allows the receiver to orthogonalize the link. The main benefits of this orthogonalization are the easy realization of the transmit diversity for the offset-featured SQOSPK, and the removal of the noise correlation at the input to the space-time decoder and the elimination of I/Q interference when space time orthogonalization is applied to the symbol level.
