Intended for designers and would-be designers of digital communication systems, this text extracts the common principles underlying a range of media and applications and presents them in a unified framework. Specifically, it treats the transport of bit streams from one geographical location to another over various physical media, such as wire pairs, coaxial cable, optical fibre and radio. It also treats multiple-access channels, where there are potentially multiple transmitters and receivers sharing a common medium. "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. In this Third Edition material on recent advances in wireless communications, error-control coding and multiuser communications has been added. As a result, two chapters have been added, one on the theory of MIMO channels, and the other on diversity techniques for mitigating fading. The treatment of error-control coding has been rewritten to reflect the current state of the art in 2003.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 has been 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.

This supplement contains worked solutions to the problems found in "Digital Communication", which is intended for designers and would-be designers of digital communication systems. The overall focus of the main text is on the transport of bit streams from one geographical location to another over various physical media such as wire pairs, coaxial cable, optical fibre and radio waves. In addition, there is coverage of the multiple access and synchronization issues relevant to constructing communication networks that simultaneously transport bit streams from many users. The material in this book is thus directly relevant to the design of a multitude of digital communication systems including local and metropolitan area data networks, voice and video telephone systems, digital CATV distribution, digital cellular and radio systems, the narrowband and broadband integrated services digital network (ISDN), computer communication systems, voiceband data modems and satellite communication systems. The common principles underlying these and other applications are extracted and presented in a unified framework.In the second edition existing material has been extensively revised and new material has been added. Two major topics which are emphasized are the combination of coding with intersymbol interference, and fading channels and wireless communicaton. Chapters 6-8 of the first edition have been completely rewritten and have become Chapters 6-10 in the second edition. In addition, solutions have been added to the exercises at the end of the book. This work is suitable as a first-year graduate textbook and should also be of interest to many professionals in industry. The book has been made more attractive to both audiences through the inclusion of many practical examples and a practical flavour in the choice of topics.

This book concerns digital communication. Specifically, we treat the transport of bit streams from one geographical location to another over various physical media, such as wire pairs, coaxial cable, optical fiber, and radio waves. Further, we cover the mul­ tiplexing, multiple access, and synchronization issues relevant to constructing com­ munication networks that simultaneously transport bit streams from many users. The material in this book is thus directly relevant to the design of a multitude of digital communication systems, including for example local and metropolitan area data net­ works, voice and video telephony systems, the integrated services digital network (ISDN), computer communication systems, voiceband data modems, and satellite communication systems. We extract the common principles underlying these and other applications and present them in a unified framework. This book is intended for designers and would-be designers of digital communication systems. To limit the scope to manageable proportions we have had to be selective in the topics covered and in the depth of coverage. In the case of advanced information, coding, and detection theory, for example, we have not tried to duplicate the in-depth coverage of many advanced textbooks, but rather have tried to cover those aspects directly relevant to the design of digital communication systems.

Specifically, we treat the transport of bit streams from one geographical location to another over various physical media, such as wire pairs, coaxial cable, optical fiber, and radio. We also treat multiple-access channels, where there are potentially multiple transmitters and receivers sharing a common medium. Ten years have elapsed since the Second Edition, and there have been remarkable advances in wireless communication, including cellular telephony and wireless local-area networks. This Third Edition expands treatment of communication theories underlying wireless, and especially advanced techniques involving multiple antennas, which tum the traditional single-input single-output channel into a multiple-input multiple-output (MIMO) channel. This is more than a trivial advance, as it stimulates many advanced techniques such as adaptive antennas and coding techniques that take advantage of space as well as time. This is reflected in the addition of two new chapters, one on the theory of MIMO channels, and the other on diversity techniques for mitigating fading. The field of error-control coding has similarly undergone tremendous changes in the past decade, brought on by the invention of turbo codes in 1993 and the subsequent rediscovery of Gallager's low-density parity-check codes. Our treatment of error-control coding has been rewritten to reflect the current state of the art. Other materials have been reorganized and reworked, and three chapters from the previous edition have been moved to the book's Web site to make room.
