Spread Spectrum CDMA offers a comprehensive overview of 2G and 3G cellular implementations of Code Division Multiple Access (IS-95 and IS-2000). Beginning with a basic description of the typical wireless link (e.g. RF propagation, link budget analysis, digital modulation), the text then progresses the reader through an understanding of how CDMA works (e.g. the use of Pseudo-Random Noise codes and orthogonal Walsh Codes, Direct Sequence Spreading gain, recovering energy previously lost via multipath reflections), and the significant advantages CDMA offers in a multi-user environment over existing 2G/3G wireless technologies. To provide something of a "real world" application of CDMA in action, the text also offers a basic "day-in-the-life" overview of a generic CDMA cell phone operating on a typical wireless network. This book is highly recommended for technicians and engineers with a basic background in wireless technologies, and who are looking to expand that knowledge to understand how Direct Sequence Spread Spectrum CDMA works, and the advantages it offers in improving the capacity of a wireless system in a multi-user environment.

In the past 7 years CDMA (Code Division Multiplexed Access) has grown from a small experiment to the technology that is going to replace all existing wireless methods in North America and around the world, replacing even GSM, which up to now has been deeply entrenched in Europe and elsewhere. Though many books cover it conceptually, there are few that deal in the application of CDMA to the day-to-day functioning of the wireless network. This book is focused on the workplace needs of RF managers and engineers. Mathematically difficult material has been culled from the body of the book and placed in carefully organized appendices, so readers have access to derivations but don’t have to wade through them to find the solutions they’re looking for. And unlike any existing CDMA book, this details the similarities and differences between the 2G IS-95 and 3G IS-2000 standards, focusing on the many issues that changeover is going face.From the Back Cover:
CDMA AT WORK
* Progressive explanation of IS-95 and IS-2000, 2G and 3G CDMA from basic principles to actual application
* Progressive conceptual development from the Physical layer to the Network layer, including typical real-world conditions such as fading, handoffs, etc.
* “Day in the life” walkthrough of several actual CDMA network issues and experiences
* Complete with several software applications, including a brief graphical simulation of a realistic network diagnostic monitor
The unparalleled ability of CDMA (Code Division Multiple Access) to increase network capacity while providing enhanced data services is driving its growth worldwide. And if working CDMA solutions for RF networks—both now and in the transition from IS-95 to IS-2000—is what you need, you’ve come to the right place. CDMA expert Steve Lee’s Spread Spectrum CDMA provides a user-friendly explanation of the concepts, issues, and techniques behind the IS-95 and IS-2000 CDMA standards. This book is a must for those seeking to:
* Gain an understanding of the principles behind CDMA and RF communications in general
* Understand the variety of real-world issues CDMA addresses, including network capacity, multipath, and enhanced services
* Explore the forward and reverse link messaging protocols
* Develop a practical view of the motives and techniques driving the transition from 2G to 3G CDMA
* Discover a practical understanding of CDMA, in a walkthrough of the daily functions of a CDMA network
* Explore some of the more fundamental aspects of RF communications, from a practical to a mathematical approach
