Description

For second and third year introductory communication systems courses for undergraduates, or an introductory graduate course.

This revision of Couch’s authoritative text provides the latest treatment of digital communication systems. The author balances coverage of both digital and analog communication systems, with an emphasis on design. Students will gain a working knowledge of both classical mathematical and personal computer methods to analyze, design, and simulate modern communication systems. MATLAB is integrated throughout.

Features

MATLAB illustrative examples and plots and practice in files.

Minimum-level mathematics used throughout.

Communication system building blocks – Describes down converters, phase-locked loops and other essential blocks used in receivers and transmitters.

Noise performance analysis of communication systems.

Case studies of modern communication systems.

Discussion of communication system standards.

Over 500 problems with selected answers.

Study-aid examples and homework problems, many of which are computer-based and marked with a personal computer icon.

Extensive pedagogy – Includes chapter objectives, summaries, lists of key terms, and a glossary with extensive references.

New to this Edition

  • Addition of over 100 examples with solutions that are distributed throughout the chapters of the book. Most of them have MATLAB computer solutions obtained via electronic M files which are downloaded free-of-charge from author’s Web site.
  • Includes up-to-date descriptions of popular wireless systems, LTE (long-term evolution) and WiMax 4G cellular systems, and personal communication applications.
  • Includes latest updates on digital TV (DTV) technology.
  • Brings terminology and standards up-to-date.
  • Brings references up-to-date.
  • Updates all chapters.
  • Includes additional and revised homework problems.
  • Includes suggestions for obtaining the latest information on applications and standards by using the appropriate keyword queries on internet search engines, such as Google.
  • To aid in training new communication engineers, the emphasis remains on MATLAB computer solutions to problems. The electronic files for the MATLAB solutions are available online (free download) to save students time and avoid the errors that occur while typing lines of code listed in a textbook.
  • Updates all MATLAB files to run on Version R2010b.
  • Extends list of Answers to Selected Problems at the end of the book, with MATLAB solutions if appropriate.
