Book Communication Over Fading Dispersive Channels

Available in PDF, EPUB and Kindle. Book excerpt: The transmission of digital information over a fading dispersive channel is considered, subject to a bandwidth constraint on the input signals. A specific signaling scheme is proposed, in which information is transmitted with signals formed by coding over a set of smaller basic signals, all of which excite approximately independent and orthogonal outputs. The problem is then modeled as one of block coding over successive independent uses of a diversity channel. Upper and lower bounds to the minimum error probability attainable by such a scheme are derived. These bounds are exponentially decreasing in terms of the time available for information transmission, and agree asymptotically for a range of rates. These bounds are used to interpret the significance of different signal and channel parameters, and the interplay between them. Some conclusions are drawn concerning the nature of good input signals, the major one being that any basic signal should be transmitted at one of a small number of discrete voltage levels. Several numerical examples are included, to illustrate how these results may be applied in the estimation of performance levels for practical channels. (Author).

Book Wireless Communication Through Fading Dispersive Channels

Download or read book Wireless Communication Through Fading Dispersive Channels written by Dr Jyoteesh Malhotra and published by LAP Lambert Academic Publishing. This book was released on 2011-04 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wireless fading channel has not only swamped many a system designs for the last many years but its increasing significance is apparent with the advent of ubiquitous access applications. Keeping in focus the channel fading as the significant impairment, the primary goal of this book is to present a simplified analysis to compute the performance of different wireless systems characterized by a variety of modulation/detection types and fading channel models. This book is extremely helpful in this goal in that it offers for the most part tractable expressions for such parameters as the Amount of fading, average signal to noise ratio, outage probability, and the average bit error probability. Coverage includes: Mathematical characterization of cascade and Compound fading channels Simplified expressions for performance analysis that heretofore available in complex functional forms Semi-analytical evaluation of UWB systems Wireless Communication through Fading Dispersive Channels, is an essential resource for senior undergraduate students, researchers and practicing engineers responsible for evaluating their performance.

Book Digital Communication over Fading Channels

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.

Book Communications Over Fading Channels with Partial Channel Information

Download or read book Communications Over Fading Channels with Partial Channel Information written by Xinmin Deng and published by . This book was released on 2005 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of system parameters upon the performance are quantified under the assumption that some statistical information of the wireless fading channels is available. These results are useful in determining the optimal design of system parameters. Suboptimal receivers are designed for systems that are constrained in terms of implementation complexity. The achievable rates are investigated for a wireless communication system when neither the transmitter nor the receiver has prior knowledge of the channel state information (CSI). Quantitative results are provided for independent and identically distributed (i.i.d.) Gaussian signals. A simple, low-duty-cycle signaling scheme is proposed to improve the information rates for low signal-to-noise ratio (SNR), and the optimal duty cycle is expressed as a function of the fading rate and SNR. It is demonstrated that the resource allocations and duty cycles developed for Gaussian signals can also be applied to systems using other signaling formats. The average SNR and outage probabilities are examined for amplify-and-forward cooperative relaying schemes in Rayleigh fading channels. Simple power allocation strategies are determined by using knowledge of the mean strengths of the channels. Suboptimal algorithms are proposed for cases that optimal receivers are difficult to implement. For systems with multiple transmit antennas, an iterative method is used to avoid the inversion of a data-dependent matrix in decision-directed channel estimation. When CSI is not available, two noncoherent detection algorithms are formulated based on the generalized likelihood ratio test (GLRT). Numerical results are presented to demonstrate the use of GLRT-based detectors in systems with cooperative diversity.

Book Decision feedback Equalization for Digital Communication Over Dispersive Channels

Download or read book Decision feedback Equalization for Digital Communication Over Dispersive Channels written by Michael Edward Austin and published by . This book was released on 1967 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: A decision-theory approach to the problem of digital communication over known dispersive channels is adopted to arrive at the structures of the optimal and two sub-optimal receivers: the 'conventional' and 'decision-feedback' equalizers, both employing matched and transversal filters. The conventional equalizer is similar to some equalization modems finding current application, while the new decision-feedback equalizer (as its name implies) utilizes its previous decisions in making a decision on the present baud.
