Spread spectrum technology as a mature technology. communications and other fields have a wide range of applications. Book concepts of spread spectrum technology described in depth on the basis of a comprehensive introduction spread-spectrum systems. Author based on many years of teaching practice and understanding of the law. the contents of the system for re-regulate. according to the system components. will be introduced together with hair and retractable. This book is divided into eight chapters. describes the basics of spread spectrum technology. pseudo-random sequence. DS systems. frequency hopping system. the spreading code capture. spreading code tracking. spread-spectrum technology. networking. Finally spread spectrum system the realization of the main module. and a brief introduction to the use of the basic principles of pseudo-code ranging. This book is the author of the long-term teaching and research. based on the formation. as a communications and electronics engineering colleges undergraduate majors. graduate textbooks. but also as engineers and technical staff reference.
