    Publication Year: 1988, Page(s):S135 - S139
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (815 KB)

    Although radio-wave propagation has been studied over a considerable period of time, there is a continuing and expanding need for new studies. The requirements for communication, and particularly for the transmission of data signals, necessitate studies in more detail than previously, if reliable statistics for the determination of system performance are to be established. New technologies open up... View full abstract»

  • Two frequency coherence measurements on a 55GHz mobile radio link

    Publication Year: 1988, Page(s):S140 - S144

    Results obtained from a bandwidth study of multipath propagation at 55 GHz in a heavily built-up urban area are presented. A series of experiments in which two phase-correlated signals are transmitted at various frequency separations is described. Results indicate that 25 MHz is a good estimate for the coherence bandwidth in an urban multipath environment. View full abstract»

  • Measurements and characterization of the UHF mobile radio channel. Part 1: Measurements over the band 853ߝ885 MHz

    Publication Year: 1988, Page(s):S145 - S156
    Cited by:  Papers (4)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1302 KB)

    The design of a wideband measuring system using a frequency stepping technique is presented. The system measures the amplitude and differential phase (group delay) variations of a pair of spaced frequencies over the bandwidth 850ߝ960 MHz. The measurements are made when the vehicle carrying the receiver is stationary. Hence the Doppler shifts and spread of the signal observed by the moving receiver... View full abstract»

    The large area characterization of the UHF mobile radio channel over the band 869ߝ877 MHz for three different types of environment is presented. The results, representing the variations of the statistical parameters of the frequency coherence function and power delay profile, are particular to different locations in the city of Leeds, UK. The variations of the statistical parameters, which are coh... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1364 KB)

    Easy access to computers, and the need to justify time spent on them, has encouraged research workers studying radio wave propagation to concentrate on those tasks which would be too complex or too time-consuming to undertake by hand. This paper attempts to show that there is still a place for the simpler approach. None of the studies mentioned in it has made use of anything more complicated than ... View full abstract»

  • The effects of atmospheric convective circulation on a narrow radio beam

    Publication Year: 1988, Page(s):S185 - S194
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1203 KB)

    In considering the basic mechanism of heat exchange by convective circulation in the atmosphere it is apparent that the resultant thermal cell structure, as proposed by Bénard, may possess refractive index properties which will influence the cross-sectional shape of a narrow conical radio beam. A simplified classical toroidal cell is considered for the purpose of analysis to show that the core of ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1542 KB)

    Close to a high-power UK television station operating at frequencies around 800 MHz, reception difficulties were experienced by viewers owing to adverse height-gain characteristics up to 10 m above ground level, Most of the terrain between the station and the viewers was uncluttered and fully illuminated by the transmitting antenna within a radius of 4 km and so computer modelling of the soil scat...

  • Basic physics of the ionosphere: a tutorial review

    Publication Year: 1988, Page(s):S207 - S223
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2546 KB)

    This paper is an exposition of the basic physics of the ionosphere, according to the present understanding. It concentrates on the large-scale ionospheric structure at heights above 100 km. Since the ionosphere depends greatly on the structure and dynamics of the neutral atmosphere from which it is formed, and on the geomagnetic field, brief descriptions of these are given. The paper then reviews ... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (659 KB)

    Power-generating wind turbines are becoming more widespread and of larger size. Evidence of distortion caused to terrestrial television broadcast services by some of these prompted the IBA into studying the problem, the results of which are given in this paper. These results should have some relevance to any form of radio wave service. Some references are given to existing literature, the theory i... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1852 KB)

    The influences of the Earth's atmosphere are considered for radio wave propagation in the frequency range 50 to 70 GHz, with particular attention to the dominant attenuation by molecular oxygen and the effects of both hydrometeors (including rain, snow, hail and fog) and atmospheric turbulence. The possibilities, ranges and limitations of transmission systems operating within this frequency band, ... View full abstract»

    Measurements have been undertaken as a part of the first phase of an investigation concerned with propagation into buildings. A series of trials has been conducted within the University of Liverpool precinct aiming to determine the building penetration loss of transmitted signals at 441, 900 and 1400 MHz. The tests were devised to study the first-order statistics of the signal inside buildings whe... View full abstract»
