Digital communication

Edición de la obra Digital communication

Digital Communication, Second Edition 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 fiber 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 telephony 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 emphasized are the combination of coding with intersymbol interference, and fading channels and wireless communication. Both of these topics have been very active in the literature and in commercial application since the First Edition. Chapters 6 through 8 of the First Edition have been completely rewritten and have become Chapters 6 through 10 in the Second Edition. In addition, solutions have been added to exercises at the end of the book. Digital Communication, Second Edition is suitable as a first-year graduate textbook and will 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 flavor in the choice of topics.
