Designing cdma 2000 Systems

Description:

Over the past few years the wireless technology industry has seen massive growth with ever increasing mobile subscriber rates. Simple analog radio tools have evolved into sophisticated adaptive technologies. These now employ advanced hardware, modulation and coding techniques and processing solutions, unimaginable a decade ago. Network designs based on CDMA 2000 are becoming extremely complex and highly standardized. Designing CDMA 2000 Systems provides engineers with the background information needed to understand the CDMA 2000 technology, by describing design techniques and available algorithms.

This book:

• Covers the main standards involved in the technology specification whilst focussing on those aspects required for the design of CDMA systems.
• Describes in detail the structure of CDMA 2000 systems and provides guidelines for their optimisation.

Written in a thorough and knowledgeable manner this book fills a gap in the information available today and will serve as a reference for designers and operators. Its specialist coverage from introductory to advanced level serves as an excellent 'how to' manual for all those looking for one complete source on CDMA 2000
