Повний текст джерелаUnder senare år har intresset för multi-carrier modulering ökat på grund av dess höga spektrumeffektivitet under antagandet om slät frekvensfäding. Den vanligaste multicarrier moduleringen i praktiken är CP-OFDM. Denna modulering tillåter användning av enkla equalizeringsmetoder och MIMO transkodare vilket behåller ortogonalitet mellan vågformerna. Däremot tillåter den inte någon flexibilitet i val av vågform och är inte heller helt spektraleffektiv. På grund av inflexibilitet i val av vågform är dess prestanda begränsad under till exempel frekvensmultiplexing (FDMA). För att förbättra prestandan hos CP-OFDM ¨ar det viktigt att ha en modulering med möjlighet att en vågform begränsad i både tid och frekvens. Grey analys visar att det enda sättet att uppnå full spektrumeffektivitet, i kombination med vågformer som är väl begränsade i både tid och frekvens, är att ge upp ortogonaliteten i komplexa fältet. Filter Bank Multi-Carrier (FBMC) med Offset-QAM (OQAM) är ett alternativ som uppnår detta. I den här avhandlingen studeras just denna modulation, hur det är möjligt att göra effektiv modulation och demodulation, men också hur dess equalizer, pre-kodare och transkoder används vid multi-tap och MIMO-kanaler. En annan modulation, baserad på FBMC med OQAM, är cyclisk offset-QAM (COQAM). COQAM försöker göra avvägning mellan spektral effektivitet och enkelhet av utjämnings- och transkodrar metoder. I den här avhandlingen studeras både FBMC-baserade modulationer och COQAM i en rad olika scenarios: osynkroniserade multianvändare, osynkroniserad upplänk, flera vägar kanaler, SIMO, MISO och MIMO-kanaler.

Повний текст джерелаLa modulation à porteuses multiples (MCM) est une technique de transmission efficace pour les communications filaires et sans fil à débit de données élevé, où la bande passante est divisée en plusieurs sous-canaux ayant chacun leur propre fréquence porteuse. Il existe de multiples réalisations possibles pour les systèmes MCM, mais le multiplexage orthogonal par répartition en fréquence (OFDM) est la solution la plus répandue dans les applications et standards présentement en vigueur. Toutefois, en raison de l'utilisation de filtres de synthèse et d'analyse rectangulaires, certaines imperfections causées par le canal de transmission, tels que les interférences à bande étroite (NBI) et le décalage de la fréquence porteuse (CFO), peuvent dégrader de manière significative les performances d'OFDM. Par ailleurs, les futurs réseaux de télécommunication nécessiteront des débits de transmission plus élevés, une plus grande efficacité de la bande passante et plus de flexibilité dans la gestion d'utilisateurs multiples non synchronisés. Les techniques de bancs de filtres à porteuses multiples (FBMC) ont récemment attiré l'attention de nombreux chercheurs.Dans ce contexte, nous proposons tout d'abord une nouvelle méthode pour la conception des bancs de filtres sur-échantillonnés à reconstruction parfaite (OPRFB) basés sur la modulation par transformation de Fourier discrète (DFT), pour les applications de transmultiplexage dans les systèmes MCM. La propriété de reconstruction parfaite (PR) est assurée par l'utilisation d'une famille paramétrique de matrices para-unitaires dans la réalisation des filtres polyphasés utilisés pour la transmission et la réception des données. L'optimisation des paramètres de conception pour la méthode choisie a pour but de minimiser l'énergie des filtres de synthèse et d'analyse dans la bande de coupure, ce qui conduit à une amélioration du confinement spectral. Les résultats d'analyse et de simulations montrent que les bancs de filtres OPRFB donnent lieu à un avantage marqué. En particulier, on constate une réduction significative du taux d'erreurs binaires (BER) lors de la transmission de données au moyen de la structure OPRFB proposée.Notre deuxième contribution porte donc sur le développement et l'analyse d'un nouvel estimateur conjoint des paramètres CFO et la réponse impulsionnelle du canal (CIR) basé sur le principe de la vraisemblance maximale (ML) et utilisant une séquence d'entraînement connue, toujours dans un contexte à usager unique. La borne de Cramer Rao (CRB) sur la variance des estimateurs non-biaisés des paramètres CFO et CIR est également dérivée. La performance du nouvel estimateur ML est soumise à l'étude par l'entremise de simulations numériques dans des conditions réalistes, soit en présence de CFO et de canaux à évanouissements en fréquence sélectifs. Les effets de différents motifs de tonalités pilotes sur la performance de l'estimation sont également. Les résultats démontrent l'excellente performance du nouvel estimateur ML conjoint proposé, qui peut déterminer avec une grande précision les paramètres CFO et CIR inconnus dans les différentes configurations expérimentales soumises à l'étude.Notre troisième et dernière contribution traite de l'extension de ce nouvel estimateur ML au cas d'usagers multiple. Plus précisément, nous considérons l'estimation conjointe du CFO et des coefficients CIR basée sur le principe ML dans la liaison montante des systèmes de transmission OPRFB multi-usagers (MU-OPRFB). Suite à son extension au cas multi-usagers, la performance de l'estimateur ML conjoint est examinée à l'aide de simulations numériques pour différents schémas d'allocation des sous-bandes entre les usagers. En outre, différentes distributions de tonalités pilotes dans le temps sont prises en compte et leurs effets sont étudiés sur des canaux radio mobiles variant dans le temps. Le potentiel d'application du nouvel estimateur ML aux systèmes multi-usagers est démontré.

Повний текст джерелаNew use cases for wireless communications recently emerged ranging from massive sensor networks to connected cars. These applications highly differ from typical signals supported by already deployed mobile technologies, which are mainly high data rate pipes. The forthcoming generation of mobile technology, 5G New Radio, introduces the concept of signal numerology so as to properly serve the requirements of the diverse applications it will support. Indeed by considering different numerologies, the time/frequency signal allocation is made more flexible which allows to shape the transmitted signal according to its needs. However, multiplexing signals with different numerologies generates interference and therefore signal distortion. Spatial filtering, such as beamforming, is envisioned for 5G above 6-GHz communications to limit inter-user interference. However, this issue still holds for sub-6 GHz systems where spatial filtering is not considered in 5G.In this work, we consider side lobe rejection techniques to ease service multiplexing in sub-6 GHz bands. Not only it provides inter-user interference mitigation but it also improves the bandwidth use efficiency in bands where frequency is a scarce resource. A novel solution, mixing filter-bank for confined spectrum and complex orthogonality for a straightforward re-use of known-how 4G/5G techniques, is proposed. The complex orthogonality is restored thanks to an OFDM precoding substituting the commonly used Offset-QAM signaling which limits the orthogonality to the real field. Moreover, the proposed solution, named Block-Filtered Orthogonal Frequency Division Multiplexing (BFOFDM), relies on a simple 5G receiver scheme which makes it backward compatible with already deployed technologies.The BF-OFDM system model is fully described and adapted to cellular standards. Besides, different prototype filter designs methods are proposed to either improve the intrinsic interference attenuation or to better confined the spectrum of the transmitted signal. Last but not least, the proposed waveform will be compared with state-of-the-art solutions for both typical and 5G oriented evaluation scenarios such as multi-service coexistence
