The goal of this book is to provide a concise but lucid explanation and derivation
of the fundamentals of spread-spectrum communication systems. Although
spread-spectrum communication is a staple topic in textbooks on digital communication,
its treatment is usually cursory, and the subject warrants a more
intensive exposition. Originally adopted in military networks as a means of
ensuring secure communication when confronted with the threats of jamming
and interception, spread-spectrum systems are now the core of commercial applications
such as mobile cellular and satellite communication. The level of
presentation in this book is suitable for graduate students with a prior graduatelevel
course in digital communication and for practicing engineers with a solid
background in the theory of digital communication. As the title indicates, this
book stresses principles rather than specific current or planned systems, which
are described in many other books. Although the exposition emphasizes theoretical
principles, the choice of specific topics is tempered by my judgment of
their practical significance and interest to both researchers and system designers.
Throughout the book, learning is facilitated by many new or streamlined
derivations of the classical theory. Problems at the end of each chapter are
intended to assist readers in consolidating their knowledge and to provide practice
in analytical techniques. The book is largely self-contained mathematically
because of the four appendices, which give detailed derivations of mathematical
results used in the main text.
