Code division multiple access (CDMA) has become a preferred choice of the wireless telecommunications industry. This book is the result of recent efforts by many members of the technical staff of Bell Labs at Lucent Technologies Inc. to study CDMA technology as it applies to cellular or PCS. The text summarizes the work that has been developed and applied to the design and deployment of IS-95 CDMA systems, and provides an in-depth discussion of various engineering guidelines for a multitude of real-world issues involved in the design, deployment and optimization of IS-95 CDMA systems and networks. The goal is to aid the reader in understanding the types of issues involved in engineering successful CDMA mobile communication systems and the guidelines required to deal with those issues.

To make the book more useful for those readers interested in cell planning, a demonstration version of Cellular Engineering 4 (CE4), a CDMA coverage prediction software tool developed at Bell Labs, has been included. Using this software, readers can obtain hands-on experience in CDMA cellular engineering techniques as well as in the design and analysis of CDMA networks. The North American PCS CDMA system operating at 1800 MHz is the example used for the discussions. However, almost all of the discussions are equally applicable to both 1.8 GHz and 850 MHz systems if appropriate modifications for frequency-related values are made.

The book begins with a CDMA overview and a summary of CDMA concepts and operations, then covers spectrum coordination, pilot assignment, mobile station access and paging, and handoff issues. It continues with discussions of link budgets, capacity, coverage, traffic engineering and antennas. The appendices provide a sample RF design process, an outline of RF optimization procedures and RF coverage predictions using CE4.

The book is easily understood, with clear, helpful graphics and minimal complex math. It provides practical guidelines for individuals interested or engaged in the engineering and optimization of CDMA networks.

* Advanced Techniques for Digital Receivers

Phillip E. Pace

430 pages plus software; $119, £82
ISBN: 1-58053-053-2

This book presents new electronic, electro-optic and superconductor digitization methods and emphasizes high resolution, symmetrical number system (SNS) techniques that can be applied to a variety of receiver components, architectures and receiver subsystems. The book is appropriate for senior undergraduate and first-year graduate students, and contains a disk with MATLAB/
SIMULINK programs that may be used for problem exercises that appear at the end of each chapter.

Chapter 1 presents the concepts of time domain and frequency domain signals and systems. Linear time-invariant systems are discussed and filtering concepts are introduced. Chapter 2 presents a brief overview of analog receiver architectures. New digital receiver techniques are investigated, and radar, infrared, satellite ground station, Global Positioning System and electronic warfare receivers are described. Chapter 3 explains the signal conversion process. Both electronic and optical circuits are emphasized, as well as the concept of coherent sampling. Chapter 4 describes the parameters used to measure the dynamic performance of the signal conversion process. Transfer functions of the digital-to-analog and analog-to-digital converters (ADC) are presented.

Chapter 5 provides a detailed overview of high performance signal conversion architectures, including full-flash, two-step and folding ADCs, electro-optical digital antennas, time interleaved digitizers and pipelined ADC architectures. Chapter 6 discusses oversampling theory and sigma-delta modulation, and describes first- and second-order modulators. Chapter 7 presents the theory of digital RF memories; Chapter 8 covers the application of superconductor technology to amplitude-analyzing and sigma-delta ADCs.

Chapter 9 offers a complete discussion of SNS theory, and Chapter 10 discusses SNS undersampling discrete Fourier transform receivers and their advantages. The final chapter presents phase-sample, direction-finding antenna theory. A two-channel example is shown and experimental results are demonstrated.
