Theory of Code Division Multiple Access Communication
Chapter One
INTRODUCTION TO CELLULAR
MOBILE RADIO COMMUNICATION
The subject of this book is code division multiple access (CDMA) communications.
A major application of CDMA is wireless communication including
mobile radio. In this chapter we introduce the basic concepts of mobile radio
systems, including cellular concepts, consider the general structure of a cellular
system, and study different principles of multiple-access (time, frequency, and
code division) and spread spectrum concepts.
This chapter begins with an overview of the principles of cellular radio
systems. Next, given the focus on simultaneous wideband transmission of all
users over a common frequency spectrum, we consider direct-sequence CDMA
systems, frequency-hopped CDMA systems, and pulse position-hopped CDMA
systems. The chapter concludes with a description ... read full excerpt from Theory of Code Division Multiple Access Communication ebook
