Preface
CDMA has been quite successful as a second-generation cellular system,
having achieved widespread use in particular in North America and Korea
by the turn of the twenty-first century. As the new century begins, CDMA
systems will once again find widespread use in the form of third-generation
cellular systems. However, two third-generation systems based on CDMA,
cdma2000 and WCDMA, have emerged. As a result, many people both
inside and outside the wireless industry have a distinct desire to actually be
able to distinguish between these two systems and study the relative features
of each.
Moreover, work was initiated within the standardization bodies
responsible for cdma2000 and WCDMA (namely the 3GPP2 and 3GPP
respectively) to evolve these third-generation CDMA systems to provide
improved services for cellular packet data users. This effort has resulted in
the 1X -EV system for cdma2000 and HSDPA for WCDMA.
This book is intended to give the reader an overview of the CDMA
systems presently being deployed and used for second- and third-generation
cellular telephony. The authors hope that any reader, after reading this text,
will not only be able to determine exactly what distinguishes second-
generation CDMA systems such as IS-95 from their third-generation
counterparts, but also what distinguishes cdma2000 from WCDMA.
In addition, it is intended that the reader come away with a better
understanding of the evolution of WCDMA and cdma2000. As packet data
services are expected to play a more prominent role in cellular telephony
during the first decade of the twenty-first century, these technologies will
become more important.
Chapter 1 of the text provides an introduction to cellular telephony and
the various technologies available for cellular multiple-access communica-
tions; it also provides a description as to what technologies are used in first-
generation, second-generation and third-generation systems. Chapter 2 pro-
vides the basic theory behind spread spectrum communications and CDMA
