IS-95 CDMA and cdma2000: Cellular/PCS Systems Implementation

Vijay K. Garg

Prentice Hall PTR

423 pages; $75 ISBN: 0-13-087112-5

CDMA technology has undergone major changes and has become a viable technology for third-generation (3G) systems. This book defines those aspects of CDMA that are essential to understanding system capacity, and provides guidelines for system parameters of a CDMA network. The migration path from CDMA to a 3G cdma2000 system is outlined.

The book is divided into four segments. Chapters 1 through 4 provide a foundation for understanding the subsequent chapters. Major attributes of CDMA and the access technologies for cellular/PCS systems are presented. Different types of spread-spectrum systems are described with the emphasis on direct sequence spread-spectrum techniques used in CDMA. Speech and channel coding applications in IS-95 CDMA systems are described and the concepts of diversity reception are explained.

Chapters 5 through 11 deal with IS-95 CDMA standards. A high level description of the IS-95 air interface is presented along with explanations of modulation schemes, bit repetition, block interleaving and channel coding. IS-95 CDMA call processing states, idle handoff, slotted paging, registration and authentication procedures, and other call management issues are discussed. The IS-95 handoff strategy and power control schemes for forward and reverse links are described.

The third section, involving Chapters 12 and 13, provides design aspects of a CDMA system, including a discussion of propagation models, link budgets, the transition from analog to CDMA operation, radio link capacity, facility engineering, border cells on a boundary between two service providers, and interfrequency handoff. Procedures for calculating the capacity of the reverse and forward links of a CDMA system are presented. The final section focuses on data applications in CDMA and the evolution of IS-95 (2G) to cdma2000 (3G) to satisfy the ITU IMT-2000 specification.

This book addresses the needs of practicing engineers and engineering managers in understanding CDMA concepts, system capacity and other aspects of the CDMA-based cellular/PCS networks.

CDMA Systems Engineering Handbook

Jhong Sam Lee and Leonard E. Miller

Artech House Inc.

1228 pages; $135, £93 ISBN: 0-89006-990-5

This book is written for those individuals interested in learning about the design and operational principles of the IS-95 CDMA spread-spectrum cellular system and related PCS systems. The book is a tutorial based on material from extensive courses conducted in Korea and the US.

The book begins with a review of the fundamental concepts of spread spectrum and CDMA systems, including sampling theory, waveshaping for spectrum control and the use of probability functions in system analysis. Chapter 2 provides an overview of radio propagation loss models and mobile radio channel models, and the use of these models in cellular design. Chapter 3 explains the fundamentals of telephone traffic theory, conventional cellular system architecture and cellular engineering tradeoffs. Chapter 4 offers a systematic summary of the main features of the CDMA common air interface standard.

Chapter 5 provides the theory and application of the Walsh functions used for orthogonal multiplexing on the IS-95 forward link and for orthogonal modulation on the reverse link. Several methods for generating and demodulating Walsh functions are described. Chapter 6 discusses the mathematical background of the pseudorandom noise (PN) sequence generators used in IS-95.

Chapter 7 deals with modulation and demodulation of IS-95 spread-spectrum signals. Chapter 8 describes the theory and practice of convolutional codes leading up to their use in CDMA cellular system applications. Chapter 9 explains diversity techniques and Rake processing, including generic diversity techniques, such as selection diversity, equal gain diversity, and maximal ratio combining.

Chapter 10 describes CDMA cellular system design and Erlang capacity. The CDMA cellular system forward and reverse link power budgets are examined in detail, and methods for characterizing CDMA cell size are presented. The final chapter deals with CDMA optimization issues.
