Drawing upon his experience in building the first major CDMA network in North America, Samuel Yang explains the essentials of CDMA wireless technology, helping the reader acquire the knowledge needed to engineer and implement an IS-95 based CDMA system. Examining both the theoretical and practical side of CDMA engineering, this guide is designed for practicing RF and system engineers who should find the modular-oriented chapters on spread-spectrum multiple access technique, design and performance engineering, CDMA traffic engineering, and regulatory implications especially useful.
