Spread Spectrum CDMA : IS-95 and IS-2000 for RF Communications

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.
