Overview
This book is for designers and would-be designers of digital communication systems. The general approach of this book is to extract the common principles underlying a range of media and applications and present them in a unified framework. Digital Communication is relevant to the design of a variety of systems, including voice and video digital cellular telephone, digital CATV distribution, wireless LANs, digital subscriber loop, metallic Ethernet, voiceband data modems, and satellite communication systems.
New in this Third Edition:
New material on recent advances in wireless communications, error-control coding, and multi-user communications has been added. As a result, two new chapters have been added, one on the theory of MIMO channels, and the other on diversity techniques for mitigating fading.
Error-control coding has been rewritten to reflect the current state of the art.
Chapters 6 through 9 from the Second Edition have been reorganized and streamlined to highlight pulse-amplitude modulation, becoming the new Chapters 5 through 7.
Readability is increased by relegating many of the more detailed derivations to appendices and exercise solutions, both of which are included in the book.
Exercises, problems, and solutions have been revised and expanded.
Three chapters from the previous edition have been moved to the book’s Web site to make room for new material.
This book is ideal as a first-year graduate textbook, and is essential to many industry professionals. The book is attractive to both audiences through the inclusion of many practical examples and a practical flavor in the choice of topics.
Digital Communication has a Web site at : http://www.ece.gatech.edu/~barry/digital/, where the reader may find additional information from the Second Edition, other supplementary materials, useful links, a problem solutions manual, and errata.
Synopsis
Intended for designers of digital communications systems, this volume identifies common principles underlying an array of media and applications, and then situates these principles within a unifying framework. Chapters address topics like deterministic signal processing, stochastic signal processing, the limits of communication, pulse-amplitude modulation, probabilistic detection, equalization, MIMO communications, fading and diversity, error control, signal-space coding, timing recovery, and multiple access alternatives. The authors teaches at the Georgia Institute of Technology and the University of California at Berkeley. Annotation ©2003 Book News, Inc., Portland, OR
Editorials
From Barnes & Noble
The Barnes & Noble ReviewThe third edition of Digital Communication is excellent, and a real find for designers in the field of transporting information over a variety of systems. Reflecting the phenomenal changes that have taken place in the industry over the years since the second edition was published, John R. Barry, Edward A. Lee, and David G. Messerschmitt do more than justice to all of those changes. Subjects are well organized and covered thoroughly, with an additional web site that holds some material from the second edition and other pertinent information.
The authors begin by defining some important mathematical terms -- such as upconverter, downconverter, and complex envelope -- for later use. Next, they focus on pulse-amplitude modulation (PAM), both passband and baseband, and then, moving beyond PAM, examine such advanced modulation techniques as orthogonal modulation and orthogonal pulse-amplitude modulation (which includes CDMA and OFDM as special cases). Taking a probabilistic approach to the detection problem that goes well beyond white-Gaussian noise, Barry and his team examine the fundamentals of multiple-input, multiple-output communications and emphasize multiuser detection. Finally, they describe diversity techniques exploiting antenna arrays for mitigating multipath fading and look at low-density parity-check codes, including Tanner graphs, message-passing decoding, and density evolution.
If you design or engineer digital communications systems or technologies, Digital Communication belongs in your arsenal. John R. Vacca
