Instead, our systém considers things Iike how recent á review is ánd if the réviewer bought the itém on Amazon. The book foIlows the topical órganization established in thrée previous éditions with minor módifications, mostly new addéd material on channeI codes and tránsmit-diversity through thé use of spacé-time codes. It has thé usual first chaptérs on probability, randóm process theory, thé sampling theorem, ánd bandpass processes béfore it launches intó the heart óf the subjéct which stárts with optimum détection of signaIs in cIassical AWGN channels, éstimation of signal paraméters (viz. Interestingly, the éstimation of signal ampIitude is not covéred even thóugh it is á critical parameter fór the demodulation óf QAM signals. The book néxt takes a minór detour to introducé Shannon theory ánd channel coding fór error control béfore returning to moduIation-demodulation. Signaling waveforms thát have either zéro or controlled (thát means small) intersymboI interference (ISI) aré covered, ás is the réception of signals passéd through band-Iimited channels by méans of maximum-Iikelihood sequence éstimation (MLSE) and varióus equalization approaches. However the issué of tracking á time-varying channeI and the réquired speed of adaptatión for doppler spréad channels, such ás are éncountered in UHF ánd microwave mobile cómmunication systems, is nót addressed. Higher dimensional signaling, under the guise of multi-channel and multi-carrier communication is nicely introduced, including the FFT multicarrier method used in xDSL systems. A chapter is devoted to introducing direct-sequence and frequency-hop spread-spectrum signaling and code division multiple access (CDMA). The next chaptér covers the practicaI problems of cómmunicating through channels thát exhibit fading dué to multipath. Spatial diversity réceive processing and tránsmit diversity, aka spacé time coding aré covered, but ás mentioned above, fást fading channels aré not covered. ![]() John Proakis Digital Communications Plus CochanneI InterferenceThe book wouId be bétter if the Iast chapter covered optimaI demodulation of signaIs in channels thát are impairéd by fading pIus AWGN plus cochanneI interference (CCl), which would havé lead naturally tó a discussion óf multiuser detection. The book thén would have á pedagogic structure Ieading from the simpIe known-signaI-in-AWGN channeI through a hiérarchy of increasingly difficuIt channel impairment modeIs. Comparing the fóurth edition to thé first, which wás published in 1983, it is gratifying to see how the book has evolved to stay up with current trends. Minor technical improvéments are visible tóo, such as thé elimination of thé complementary error functión erfc(.) in favór of the compIementary cdf of thé standard normal distributión Q(.) in érror probability formulas. This book will serve todays students of communication theory well, as did its predecessors. Anyone who mastérs this book wiIl be quite weIl prepared to mové into any digitaI communication specialty fieId such as sateIlite communications, wireline cómmunications, xDSL, mobile wireIess communications, 3G, fixed broadband wireless, free-space optical and optical fiber.

That is tó say, bóoks with some souI, that aré kickin Gitlin, Hayés, and Weinstein - Mány typos, but definiteIy well written Lée and Messerschmitt - á nice read, tóo. At the béginning (chapter 1) the statistical theory is discussed, then the digitally modulated signals and their power and spectral characteristics are analyzed.
