This book was released on 1993 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report derives expressions for the average probability of symbol error of coherent M-ary phase-shift-keyed (M-PSK) communication system operating under the following nonideal conditions: (1) time-invariant multipath channel consisting of a direct path and a single multipath, (2) intentional/ unintentional interference consisting of either a continuous wave (CW) signal or a bandpass filtered white Gaussian noise signal (bandwidth is variable), and (3) additive white Gaussian noise. Exact solutions are derived for coherent binary phase shift-keyed (BPSK) while both exact and upper bound solutions (shown to be tighter than the Chernoff bound) are derived for coherent M-PSK. One particular example, line-of-sight ultrahigh frequency (LOS UHF) radio, is used extensively to exercise the derived expressions and illustrate typical system performance. These results pertain to receiver with no means of compensation for the nonideal channel conditions. Methods of compensation for multipath and interference, like adaptive equalization, beamforming, spatial diversity, and multichannel adaptive equalization, are presently under investigation by the authors. The results in this report will help determine the performance gain offered by these methods of compensation.

Download or read book Digital Communication over Fading Channels written by Marvin K. Simon and published by John Wiley & Sons. This book was released on 2005-02-11 with total page 936 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Effect of Multipath on Digital Communications Systems With Application to Space Station written by William J. Toti and published by . This book was released on 1986 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analysis of the effect of multipath propagation on digital communications systems was conducted. A brief overview of the root causes of multipath propagation was included in this discussion. Probabilities of error were then derived for a generalized digital communications system experiencing Rician fading due to multipath propagation. Exact results were obtained for equiprobable M-ary Frequency Shift Keyed and M-ary Phase Shift Keyed modulation schemes used to transmit digital data. Furthermore, the probability of error was obtained for a generalized digital communication system experiencing single-bit Intersymbol Interference due to multipath propagation. Finally, the performance of digital communication links for NASA's Space Station operating in the presence of Intersymbol Interference was evaluated. Results obtained tend to show that severe communication system performance degradation may occur on those links under certain transmitter/receiver and Space Station geometries. (Thesis).
