دیجیتال ارتباطات از محو شدن کانال ها: رویکرد یکپارچه به تجزیه و تحلیل عملکرد Digital Communication Over Fading Channels: A Unified Approach to Performance Analysis

A unified presentation, broad coverage, single-volume convenience This timesaving reference provides a unified approach to the performance analysis of digital communication systems over generalized fading channels. Employing alternative forms of such classical mathematical functions as the Gaussian Q-function, the Marcum Q-function, and the incomplete Gamma function, the book expresses communication system error probability performance in terms of the moment generation function (MGF) of the fading process. This MGF-based approach provides the unifying backbone of the book. Digital Communication over Fading Channels discusses in detail coherent, differentially 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 also includes single- and multichannel reception and, in the case of the latter, a large variety of diversity types. For each combination of communication type, channel fading model, and diversity type, the average bit error rate and/or symbol error rate is expressed in an easy-to-evaluate form. Special features include: * Important results previously scattered over many publications-now in a single volume * Simplified results heretofore available only in complex forms * Extremely broad coverage of topics * Explores practical applications, including the problem of optimum combining in the presence of co-channel interference Content: Chapter 1 Introduction (pages 1–13): Chapter 2 Fading Channel Characterization and Modeling (pages 15–30): Chapter 3 Types of Communication (pages 31–66): Chapter 4 Alternative Representations of Classical Functions (pages 67–97): Chapter 5 Useful Expressions for Evaluating Average Error Probability Performance (pages 99–139): Chapter 6 New Representations of Some PDF's and CDF's for Correlative Fading Applications (pages 141–153): Chapter 7 Optimum Receivers for Fading Channels (pages 155–191): Chapter 8 Performance of Single Channel Receivers (pages 193–258): Chapter 9 Performance of Multichannel Receivers (pages 259–433): Chapter 10 Optimum Combining: A Diversity Technique for Communication Over Fading Channels in the Presence of Interference (pages 435–471): Chapter 11 Direct?Sequence Code?Division Multiple Access (pages 473–494): Chapter 12 Coded Communication Over Fading Channels (pages 495–534):
