CDMA (Code Division Multiple Access) is one type of multiple access system used in radio communication. Other multiple access methods include TDMA, FDMA, etc. WCDMA (Wideband Code Division Multiple Access) is the main air interface used for third generation mobile communication systems - UMTS (Universal Mobile Telecommunication System) and is characterised by a wider band than CDMA. WCDMA uses a wider radio band than CDMA, which was used for 2G systems, and has a high transfer rate and increased system capacity and communication quality by statistical multiplexing, etc. WCDMA efficiently utilises the radio spectrum to provide a maximum data rate of 2 Mbit/s. Third generation mobile communication systems are scheduled for operational startup in Japan and Europe in 2001-2002. Applying high-speed data transfer and state-of-the-art radio terminal technology, third generations systems enable multimedia and are currently in the process of being standardised under 3GPP. Among the three types of system to be standardised (i.e. WCDMA, MC-CDMA, UTRA TDD), Japan and Europe will adopt WCDMA in a strategy to take the lead through superior service. This volume will cover the latest theoretical principles of WCDMA and explain why these principles are used in the standards. Starting with a general overview, the more advanced material is then gradually introduced providing an excellent roadmap for the reader. * Presents comprehensive coverage of the theoretical and practical aspects of WCDMA * Provides a detailed roadmap by presenting the material step-by-step for readers from differing backgrounds * Systematically presents the latest results in the field Ideal for Engineers, academics and postgraduate students involved in research and development, engineers involved in management and administration.

Get a clear, complete debriefing on the current status of the third generation radio interface technology now being standardized by the international body 3GPP. This timely new work, written by Europe's leading mobile communications researchers from manufacturing, operators, and academia, gives you a thorough explanation of the basic principles of multiple access technologies, including receiver algorithms, coding, and modulation, to help you stay up-to-date with the development of third generation systems. Much of the research presented here originated in the FRAMES (Future Radio Wideband Multiple Access System) Project, which was partly funded by the European Commission. It served as the basis for ETSI's decision to adopt W-CDMA/TD-CDMA as the air interface standard for third generation systems, as well as for the actual specification work in 3GPP.
