TABLE OF CONTENTS The commercial CDMA systems are mainly classified into two groups. One group is the synchronized CDMA systems, such as IS-95-like and cdma2000-like systems. The other group is the unsynchronized CDMA systems, such as WCDMA-like systems.
In this book, we are mainly concerned with evaluating the capacity of the synchronized CDMA systems in various aspects of capacity definition. All contents in the book, however, can be applicable to WCDMA-like systems that have an asynchronous network if the asynchronous aspects such as code synchronization, cell acquisition, and handover synchronization are properly considered when evaluating the capacity. The remaining part of this book consists of 11 chapters. In this section, we present the organization of this book and, outline the important contributions of each chapter.
In Chapter 2, the capacity of CDMA systems supporting various service classes is analyzed with respect to the maximum number of simultaneous users where each user is characterized by its own QoS requirements. In the multiclass CDMA systems, the QoS requirements are composed of a quality ( E b/N o) requirement and a transmission rate requirement [27], [28]. Different services require different received signal power levels; thus, the amount of interference generated by one service user is different from that generated by another service user. The upper limit for the number of users of one service subsequently is limited by the numbers of users in the other services. To fully utilize the multimedia CDMA system resources, the system capacity must...
