W-CDMA Mobile Communication Systems

NTT DoCoMo became the first in the world to launch a next-generation mobile phone service that enables large-capacity communications. The W-CDMA mobile communications system, known as one of the third-generation standards, was adopted in order to create such a high-speed, high-quality service. Written by leading engineers working at the forefront of research and development of W-CDMA, this volume describes, in detail, the basic technologies that constitute this mobile communications system and individual systems which are expected to play an important role in future implementations.

• Reviews various cellular systems, describes their characteristics and discusses the objectives of IMT-2000 and the status of standardization

• Explains the mechanisms and characteristics of CDMA with respect to radio access systems and describes basic transmission and capacity enhancement technologies

• Provides a detailed explanation of radio access interfaces and radio systems designs and an introduction to mobile terminals

• Discusses ATM technologies, packet communication systems and other types of network systems

• Provides an outline of network control and equipment monitoring and administration

• Describes the multimedia signal processing technologies, systems for distributing information and processing location information and electronic authentication systems

• Forecasts the mobile radio systems and network for the future

Written with researchers, developers and operators in the mobile communications sector in mind, as well as students and end users, W-CDMA Mobile Communications System will enable a wide range of readers to gain a thorough understanding of W-CDMA.
