WCDMA for UMTS: Radio Access for Third Generation Mobile CommunicationsHarri Holma, Antti Toskala WCDMA for UMTS provides a complete picture of the Wideband CDMA (Code Division Multiple Access) air interface of the 3rd generation cellular systems - UMTS (Universal Mobile Telecommunications Systems). WCDMA is designed for multimedia communications including high quality images and video, and access to services with high data rates. These capabilities will create new business opportunities for manufacturers, operators and for the providers of content and applications. WCDMA for UMTS : * Explains the key parts of the 3GPP/WCDMA standard and provides guidelines for its efficient use * Presents network dimensioning and coverage and capacity planning of WCDMA * Introduces radio resource management algorithms in the WCDMA network * Examines the coverage and capacity of WCDMA up to 2 Mbps using numerous simulation results * Introduces the TDD (Time Divisions Duplex) mode * Discusses the co-existence of TDD and FDD (Frequency Divisions Duplex) and highlights their main differences Written by leading experts in the field , this practical approach to the key features of WCDMA will have wide-ranging appeal to research and Development Engineers, Practising Engineers, Cellular Operators, Equipment Manufacturers, Frequency Technical Managers and Students on Telecommunications courses.
