"Digital Communication" is intended for designers and would-be designers of digital communication systems. The overall focus 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 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.
