Introduction to Spread Spectrum Communications
Besides the traditional military application areas, there is a growing and intense interest in spread spectrum communications systems for evolving civil applications, e.g., cellular-mobile communications, personal communications, and satellite-mobile communications. Ideal for those who need to get up to speed or current quickly in this area, this self-contained exploration of spread spectrum system analysis and applications provides a solid theoretical background along with an abundance of examples of specific analysis/design situations, and exposes readers to the most recent research and developments in the field. Covers basic digital communication and spread spectrum concepts, and features exceptionally complete treatments of important hot topics such as spectrum spreading sequences; the code acquisition and tracking process; the effects of jamming on spread spectrum communications and the use of coding/interleaving to combat the detrimental effects of jamming; designing spread spectrum systems for low probability of the intercept; and the design of code division multiple access systems, wit h examples. Contains a complete set of technical appendices. For electrical engineers and others with a background in linear systems and probability/random processes who want a cutting-edge overview of the principles, research, and developments of spread spectrum systems.
Why Read This Book
You should read this book if you need a compact, mathematically grounded introduction to spread‑spectrum communications that balances theory with worked examples. It gets you from fundamentals (PN sequences, processing gain) to practical topics (acquisition, RAKE receivers, CDMA performance) useful for mobile, satellite, or secure wireless systems.

How It Compares
Closer in scope to R. C. Dixon's 'Spread Spectrum Systems' as a practical intro, but more concise and pedagogical; less exhaustive than Torrieri's or the Simon/Omura/Scholtz handbooks which are deeper and more up-to-date on modern CDMA techniques.
