W-CDMA Mobile Communication Systems (Hardcover)  | Released: 17/09/20

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 ofW-CDMA. If you want to deepen your interest in, and understanding of, mobile communication technologies read on.........The evolution of cellular based mobile communication systems, from the first generation (analogue) to the second generation (digital), has been made possible by solving many technical issues along the way. Efforts to develop a global standard for providing high-speed, high quality multimedia services have crystallised in the form of the third generation (3G) systems under the IMT 200 standard. The world's first 3G system has been implemented by Japan based on the latest research results and other countries are expected to follow from 2002 onwards. 3G systems are expected to bring about radical socio-economic and cultural changes that would affect people around the world. This volume reviews in detail the basic technologies applied to W-CDMA, a standard 3G mobile communications technology. The focus is to explain in layman's language the technologies that will play an important part in future developments, with reference to the latest research results.
