This 4th edition is an extensive update on transceiver design and features significant new chapters on the important emerging technology of cognitive radio, systems, and networks in commercial applications. Derived from numerous engineer training workshops, this book is ideal for digital wireless communications system designers.

Transceiver design is described as the device that both sends and receives signals and its place within the wireless communication system. Transceiver and System Design for Digital Communications, 4th edition have been significantly updated from the previous editions and the entire content has been reorganised to improve the overall flow of the book and enhance reader understanding.

Various techniques and designs are evaluated for modulating and sending digital data, allowing readers to gain a firm understanding of the processes needed to effectively design wireless data link communication systems.

This applied engineering reference covers a wide range of data link communication design techniques, including:


  • link budgets
  • dynamic range and system analysis of receivers and transmitters
  • digital modulation and demodulation techniques of phase-shift keyed and frequency hopped spread spectrum systems using phase diagrams
  • multipath
  • gain control
  • an intuitive approach to probability
  • jamming
  • reduction method using various adaptive processes
  • global positioning systems (GPS) data link
  • direction-finding and interferometers
  • broadband communications and home networking


About the Author

Scott R. Bullock has worked in both commercial wireless companies and military defence companies and offers an understanding and application to both areas. He has worked, consulted, and held positions at a number of leading companies in the industry including Omnipoint, Raytheon Missile Systems, Northrop Grumman, MKS/ENI and L3 communications Satellite Networks.

Specialising in data link design and system analysis, he currently holds 18 patents in the areas of spread spectrum wireless data links, frequency hop detectors, and adaptive filters and has published several articles in spread spectrum, data links, direction finding, multipath, adaptive filters, AGCs/PLLs.

Book readership

The book has been derived from numerous training workshops taught to engineers through private courses. The 4th edition will appeal to digital wireless communications system designers in both commercial and military sectors, in particular new engineers requiring practical design techniques and fundamental understanding of modern systems that employ digital transceivers.
