Performance Of Digital Communications Over Selective Fading Channels

Digital Communication over Fading Channels

The four short years since Digital Communication over Fading Channels became an instant classic have seen a virtual explosion of significant new work on the subject, both by the authors and by numerous researchers around the world. Foremost among these is a great deal of progress in the area of transmit diversity and space-time coding and the associated multiple input-multiple output (MIMO) channel. This new edition gathers these and other results, previously scattered throughout numerous publications, into a single convenient and informative volume. Like its predecessor, this Second Edition discusses in detail coherent and noncoherent communication systems as well as a large variety of fading channel models typical of communication links found in the real world. Coverage includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. The moment generating function (MGF)-based approach for performance analysis, introduced by the authors in the first edition and referred to in literally hundreds of publications, still represents the backbone of the book's presentation. Important features of this new edition include: * An all-new, comprehensive chapter on transmit diversity, space-time coding, and the MIMO channel, focusing on performance evaluation * Coverage of new and improved diversity schemes * Performance analyses of previously known schemes in new and different fading scenarios * A new chapter on the outage probability of cellular mobile radio systems * A new chapter on the capacity of fading channels * And much more Digital Communication over Fading Channels, Second Edition is an indispensable resource for graduate students, researchers investigating these systems, and practicing engineers responsible for evaluating their performance.

Performance of Digital Communications Over Selective Fading Channels

The performance of digital communications over selective wide-sense-stationary uncorrelated-scattering (WSSUS) fading channels is investigated. The emphasis is on the evaluation of the performance of binary differential phase-shift keyed (DPSK) and binary frequency-shift keyed (FSK) communications with primary emphasis on the effects of intersymbol interference produced by the frequency-selective character of WSSUS fading channels. The error probabilities of DPSK and FSK are evaluated for several models of WSSUS frequency-selective fading channels. The analysis is focused on the performance evaluation for Rayleigh fading channels. The expression for the probability of error for these systems are formulated in a way that allows the identification of the key parameters of the communication system. The performance of DPSK and FSK are evaluated for several signaling formats. The design parameters considered are the shapes of the basic data-pulse waveforms for both DPSK and FSK, the modulation index, and the relative phase between successive transmitted signals for FSK. It is shown that the system error probability is highly dependent on these system parameters.
