Abstract:

The beamed emission by relativistic sources moving along the magnetic dipolar field lines occurs in the direction of tangents to the field lines. To receive such a beamed radiation, the line of sight must align with the tangent within the beaming angle 1/γ, where γ is the particle Lorentz factor. By solving the viewing geometry, in an inclined and rotating dipole magnetic field, we show that at any given pulse phase the observer can receive the radiation only from specific altitudes. We find that the outer conal emission is received from higher altitudes than the inner conal components including the core. At any pulse phase, low frequency emission comes from the higher altitudes than higher-frequency emission. As an application of our model, we have used it to explain the emission heights of conal components in PSR B0329+54.

Abstract:

This paper investigates the impact of television and radio on social capital in Indonesia. I use two sources of variation in signal reception—one based on Indonesia's mountainous terrain, and a second based on the differential introduction of private television throughout Indonesia. I find that increased signal reception, which leads to more time watching television and listening to the radio, is associated with less participation in social organizations and with lower self-reported trust. Improved reception does not affect village governance, at least as measured by discussions in village meetings and by corruption in village road projects. (JEL L82, O15, Z13)

AbstractWe present small radio telescopes consisting of commercial instruments for satellite TV reception. With these radio telescopes we can observe the 12 GHz emissions from the quiet sun and solar flares. Since microwaves occurring in our environment, e.g., those from a building and a fluorescent lamp, are also detectable, such radio telescopes are useful not only for radio astronomy education but also for physics education.

Abstract:

The radio frequency spectrum constitutes a limited and strategic natural resource with high economic value, so it must be managed effectively and efficiently to obtain optimal benefits by observing national and international legal principles. Radio Community Broadcasting Institution uses limited frequency allocation in three channels, namely, in the frequency channels 202 (107.7 MHz), 203 (107.8 MHz), and 204 (107.9 MHz), with limited transmit power and area coverage. The problem in this research is the frequency overlap with other community radios in an area. The issue raised is whether it is possible to establish a new community radio in the Batang Regency area by paying attention to existing radios that have licenses in districts/cities that are in the area directly adjacent to Batang Regency by considering the limited allocation of radio frequency channels community, without the occurrence of radio frequency interference with other community radios. The purpose of this research is to solve these problems. It is necessary to have a policy in determining radio frequency users to get good quality radio broadcast reception. The method used is to analyze the frequency determination technique based on the interference analysis on other community broadcasters. By using the Radio Mobile Software for frequency repetition simulation, in this research, the results show that Batang FM Community Radio does not allow to get frequency channels for community radio operations. After all, it interferes with the Service Area of Soneta FM Radio in Pekalongan City because it does not meet the requirements for determining the frequency channel = Eu> NF, namely the Nuisance Field (NF) value of 109.7 dB is greater than the Minimum Usable Field strength (Eu) of 66 dB. In comparison, Limpung FM Radio gets radio frequency on channel 203 (frequency 107.8 MHz) because it meets the requirements for determining the frequency channel = Eu> NF, namely the Minimum Usable Field strength (Eu) 66 dB greater than the Nuisance Field (NF) of 55.7 dB.

Abstract:

The main purpose of this paper is to consider possible radio listeners’ profiles that can be used in a converging communication context. Based on literature review, we observe listeners’ role, as well as communication exchanges over radio’s history, and we think over reception in the age of convergence. We work with the habitus concept, according to Pierre Bourdieu and Norbert Elias, to analyze listeners and their relations towards radio. We also rely on Reception and on Digital Communication Studies to complement the theoretical discussion. Eight listeners categories have been created to understand these types of action regarding conventional and expanded radio.

Full text

Abstract:

The essay “Divinations” focuses on Robert Rauschenberg’s Oracle (1962-1965), a work whose making and display entailed close collaboration between the artist and the engineers Billy Klüver and Harold Hodges, both of Bell Laboratories. The piece stemmed from Rauschenberg’s interest in sound, sculptural form, and radio networks: it housed ten radios and speakers in various sculptural elements constructed from found metal objects, including ducts, window frames, a bathtub, and a car door. Audience members could turn dials that indirectly modified the volume and tuning of the radios. Walking through the sculptural installation, one experienced shifting acoustic, spatial, and visual effects. This text seeks to understand how the interactions between artist and engineers—and between sound sculpture and viewers—engaged systems of industrial and postindustrial production, broadcast radio, and audiovisual reception.

Abstract:

The article considers the reception of P. Kulish’s works in Yuri Lavrinenko’s literary works, in particular in the texts of radio broadcasts made on radio “Svoboda”. The subject of the study were the literary-critical articles and correspondence. The study involves the use of unknown archival sources. The article deals with the letters and radio broadcasts be Jurii Lavrinenko kept in the Department of Manuscripts and Textual Studies of Shevchenko Institute of Literature of the National Academy of Sciences of Ukraine. The article explains the reasons for the researcher’s interest in this figure. Yuri Lavrinenko sought to find the traditions of P. Kulish not only in the works of the writers of the “Executed Renaissance”, the “Prague School”, but also in the younger generation of writers of the Diaspora. The purpose of the radio talks about P. Kulish is to interest the readers of the creativity of this classic, especially his historical novel “Сhorna rada”. In radio broadcasts Yu. Lavrinenko draws attention to the artistic, historical and philosophical views of P. Kulish. The literary critic became a popularizer of P. Kulish’s work in the Diaspora.

Abstract:

Introduction: Radio information transmission systems with noise-like phase-shift keyed signals based on pseudo-random sequences have potential noise immunity provided by accurately tracking the delay of the received signal in the correlation receiver. When working with moving objects, the delay of the received signal varies continuously, and the reception quality for noise-like phase-shifted signals highly depends on the synchronization system operation and on the accuracy of estimating the received signal delay by the tracking system. To ensure the required signal reception quality, it is necessary to provide an informed choice of tracking system parameters, taking into account their effects, which are the random and systematic components of the delay tracking error, on the selected noise immunity indicator.Purpose: Analyzing how the errors in tracking the delay of a received phase-shift keyed signal based on a pseudorandom sequence by the synchronization system of a radio information transmission system can affect the probability of erroneous reception of an information symbol.Results: The calculation method was used to obtain families of dependencies of the probability of erroneous reception of an information symbol on the signal-noise ratio (SNR), and the values of the random and systematic components of the delay tracking error which are normalized to the capture band of the correlation receiver. It has been shown that at a fixed SNR, the values of the random and systematic components of the delay tracking error are critical for the erroneous reception probability. In all the cases discussed, all the dependencies are characterized by a slow change of the erroneous reception probability while the synchronization errors within the area of small SNR have fixed values. As the SNR value grows, the erroneous reception probability rapidly drops. To ensure the specified signal reception quality and the reliability of the selection of information symbols and messages in a radio information transmission system with noise-like phase-manipulated signals, its synchronization system requires a joint selection of the tracking system parameters, taking into account the limitations imposed by the operating conditions and technical implementation features.Practical relevance: The obtained results can be used in noise immunity analysis of radio information transmission systems with noise-like phase-shift keyed signals in a wide range of communication conditions, and in providing technical solutions for synchronization systems ensuring the required quality of signal reception.

Abstract:

The investigation of microstrip fix radio wires has gained awesome ground as of late. Contrasted and ordinary reception apparatuses, microstrip fix recieving wires have more points of interest and better prospects. They are lighter in weight, low volume, ease, low profile, littler in measurement and simplicity of manufacture and similarity. Besides, the microstrip fix reception apparatuses can give double and round polarizations, double recurrence activity, recurrence spryness, wide band-width, feedline adaptability, shaft checking unidirectional designing. In this paper we examine the microstriprecieving wire, kinds of microstrip reception apparatus, sustaining methods and use of microstrip fix radio wire with their favorable position and detriments over ordinary microwave radio wires.From this paper, design of small Microstrip patch antenna using parasitic technique for range of sight communication is proposed, having hexagonal condition ground plane. The recommended antenna has slots in the patch to obtain wideband. The antenna model is simulated using Finite component method at the rate of recurrence 2. 65 GHz to 4. 57 GHz. The antenna design demonstrates desired features for wireless communication

Abstract:

In 2011, a study was conducted to look at students’ reception of IIUM.FM, a newly launched online campus radio. Using the Technological Acceptance Model (TAM), the study found that factors such as perceived ease of use, perceived usefulness, and attitude highly influenced audience reception of the online radio. In 2016, a corresponding study, closely based on the original 2011 study was conducted to chart and identify how technological changes and developments have further affected the radio listeners today and whether the factors that determined listenership in 2011 still apply in 2016. The study employed a quantitative research design using the survey method and the questionnaire as the research instrument. A total of 238 respondents were sampled for 2011 and 271 respondents for 2016. Results from the comparisons done between the two studies identified the impact of technological change on the campus radio and offered recommendations and suggestions to the University’s relevant authorities for further improvement.

Full text

Abstract:

In a distributed cognitive radio (CR) sensor network, transmission and reception on vacant channels require cognitive radio nodes to achieve rendezvous. Because of the lack of adequate assistance from the network environment, such as the central controller and other nodes, assisted rendezvous for distributed CR is inefficient in a dynamic network. As a result, non-assisted blind rendezvous, which is unaware of its counterpart node, has recently led to a lot of interest in the research arena. In this paper, we study a channel rendezvous method based on prime number theory and propose a new multi-radio-based technique for non-assisted rendezvous with the blind and heterogeneous condition. The required time and the optimal number of radios for the guaranteed rendezvous are calculated using probability-based measurement. Analytical expressions for probabilistic guaranteed rendezvous conditions are derived and verified by Monte Carlo simulation. In addition, the maximum time to rendezvous (MTTR) is derived in closed form using statistical and probabilistic analysis. Under different channel conditions, our proposed solution leads to a substantial time reduction for guaranteed rendezvous. For the sake of over-performance of our proposed system, the simulation outcome is compared to a recently proposed heterogeneous and blind rendezvous method. The Matlab simulation results show that our proposed system’s MTTR gains range from 11% to over 95% for various parametric values of the system model.

Abstract:

Microwave atmospheric radiometry and radio, mm and sub-mm astronomy are “passive” services, i.e. not involved in any man-made transmission but only concerned with the reception of naturally occurring radio waves. The intensity of the radiation received is not subject to human control, unlike the situation for active services. All active services operate in bands occupied by natural signals of atmospheric and cosmic origin and the active service tranmissions may be powerful enough to noticeably interfere with reception of those signals by scientific services. A conflict exists for the coexistence of active and passive services in many frequency bands, which leads to a need for regulating how to share the electromagnetic spectrum. This document gives an overview of the problems of frequency sharing in the longwave region of the electromagnetic spectrum (radio to submillimetre waves).

Abstract:

Radio and the recording business have, since the beginning of the last century, had a profound impact upon existing musical life whenever and wherever they have decisively and irreversibly established themselves. Their arrival restructures and redefines the social relations of music in many aspects of its production, performance and reception. Radio and recording technologies have had a significant impact on the livelihoods of all those who one way or another try to make a living from music (composers, performers and - in Europe - publishers, for instance). Performance itself is transformed as new norms are set in place which call for new levels of technique and interpretation. Finally the conditions of musical reception are reconfigured and new `taste publics' emerge, potentially in conflict with each other, as musical life is totalised into a new and complex unity.

Abstract:

The special value of radio astronomy lies in the probing of extreme conditions in the universe, including the highest energies and the lowest temperatures. Radio waves can penetrate clouds of gas and dust to reveal objects in the universe and, in particular, in our Galaxy that cannot be seen by visible light. To achieve the highest resolution, radio telescopes in widely separate parts of our globe combine their reception to produce a synthesized image. This is a splendid example of international collaboration. Among the images visualized are pulsars, derived from the remnants of supernovae explosions, and quasar sources powered by black holes.

This system brings a significant performance improvement compared to the system which uses complex adaptive filter and a linear receiver, particularly in the case of high interference power, where its absence leads to the reception loss.

Abstract:

Random geometric hypergraphs are considered as mathematical models of large wireless computer networks. The dependences of the mathematical expectation of the number of hyper-edges in random geometric hypergraphs on the radii of reliable reception / transmission of radio signals by network nodes, as well as on the number of vertices in the hyper- graph are studied. The concepts of the shortest route in a geometric hypergraph are discussed. Calculations of the probabil- ity of connectivity of large random geometric hypergraphs, the mathematical expectation of the diameter of hypergraphs and its change with a change in the radii of the nodes are carried out. The presentation of the results is accompanied by graphs.

Abstract:

The radio signals transmitted by wireless technologies create a form of space that is pervasive but intangible to human senses. The multiplicity of radio waves is most commonly represented through the trope of ‘radio spectrum’, but this paper argues that this construct is too limited to communicate the extensive presence of radio waves in the environment, their relationship with human subjectivity, and the technical, economic, political and cultural dimensions of wireless transmission and reception. The space of wirelessness is conceptualised in this paper as a ‘spectrumscape’, a dynamic presence in the environment that is also a dimension of global flows, imbued with relationships of power and financial interests.

Abstract:

How do nationalistic media affect animosity between ethnic groups? We consider one of Europe's deadliest conflicts since WWII, the Serbo-Croatian conflict. We show that, after a decade of peace, cross-border nationalistic Serbian radio triggers ethnic hatred toward Serbs in Croatia. Mostly attracted by nonpolitical content, many Croats listen to Serbian public radio (intended for Serbs in Serbia) whenever signal is available. As a result, the vote for extreme nationalist parties is higher and ethnically offensive graffiti are more common in Croatian villages with Serbian radio reception. A laboratory experiment confirms that Serbian radio exposure causes anti-Serbian sentiment among Croats. (JEL D72, D74, J15, L82, N34, N44)

Abstract:

Abstract. This paper presents the preliminary results on the possible reception of over-horizon VHF radio signals from a FM (frequency modulation) transmitter during abnormal situations (probably in close association with earthquakes). The transmitter is FM Sendai (frequency = 77.1 MHz) and the receiving station is our university (UEC) at Chofu, Tokyo, with the transmitter-receiver distance being about 310 km. We first show a typical example of the reception of over-horizon VHF signals in which we present the amplitude behavior, azimuthal and incident angle estimation, etc. Then, we study the correlation between a signal anomaly and an earthquake and it seems that the over-horizon VHF signals observed are probably associated with earthquakes, observed about 7 to 0 days before an earthquake. The direction finding measurements have indicated that such signals are due to favorable tropospheric (but not ionospheric) conditions attributed to the effects of earthquakes.

Abstract:

Introduction: The known methods for calculating the interference immunity of radio signal reception in the presence of, for example, harmonic interference, often lead to significantly different numerical values. Each calculation technique of this type has its own algorithm for the resulting formula output, and these conclusions are based on a different level of “engineering rigor”. Purpose: To develop, оn the basis of linear transformation of coordinates, a correct method for calculating the error probability in the correlating reception of a four-fold phase-manipulated radio signal in the presence of coherent harmonic interference. Methods: Four-dimensional probability density of a vector of output voltages of the demodulator correlators in a four-fold integral was represented by a product of one-dimensional probability densities in the space of eigenvectors of the covariance matrix, in which two probability densities are Dirac delta functions. The quadruple integral is brought to double, with new integration limits defined from the plane equations bounding the integration region in this space. Results: Formulas were derived for accurate calculation of average probabilities of symbol and bit errors in coherent reception of a four-fold phase-manipulated radio signal in the presence of coherent harmonic interference. The derived exact formulas were used to plot the dependencies of the average probabilities of symbol and bit errors on the signal-to-noise ratio for the given interference-to-noise ratio and the given interference phase shift relative to the signal phase. It has been studied how the energy ratios of the signal and interference, as well as the interference phase shift, affect the probabilities of symbol and bit errors. It was found that the influence of a non-energy parameter equivalently leads to a change in the energy ratios. Practical relevance: The results of the research can be used in assessing the communication efficiency under interference. The developed technique will allow you to accurately determine the energy characteristics of a radio channel providing the required quality for the reception of transmitted messages in presence of harmonic interference.
