Spread-spectrum communication is a core area within the field of digital
communication. Originally used in military networks as countermeasures against
the threats of jamming and interception, spread-spectrum systems are now widely
used in commercial applications and are part of several wireless and mobile
communication standards. Although spread-spectrum communication is a staple
topic in textbooks on digital communication, its treatment is usually cursory. This
book is designed to provide a more intensive examination of the subject that is
suitable for graduate students and 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
manyotherbooks.My goal in this bookis to providea concisebut lucidexplanation
of the fundamentals of spread-spectrum systems with an emphasis on theoretical
principles.
