CDMA (Code Division Multiple Access) is one type of multiple accesssystem used in radio communication. Other multiple access methodsinclude TDMA, FDMA, etc. WCDMA (Wideband Code Division MultipleAccess) is the main air interface used for third generation mobilecommunication systems - UMTS (Universal Mobile TelecommunicationSystem) and is characterised by a wider band than CDMA.WCDMA uses a wider radio band than CDMA, which was used for 2Gsystems, and has a high transfer rate and increased system capacityand communication quality by statistical multiplexing, etc. WCDMAefficiently utilises the radio spectrum to provide a maximum datarate of 2 Mbit/s.Third generation mobile communication systems are scheduled foroperational startup in Japan and Europe in 2001-2002. Applyinghigh-speed data transfer and state-of-the-art radio terminaltechnology, third generations systems enable multimedia and arecurrently in the process of being standardised under 3GPP. Amongthe three types of system to be standardised (i.e. WCDMA, MC-CDMA,UTRA TDD), Japan and Europe will adopt WCDMA in a strategy to takethe lead through superior service.This volume will cover the latest theoretical principles of WCDMAand explain why these principles are used in the standards.Starting with a general overview, the more advanced material isthen gradually introduced providing an excellent roadmap for thereader.* Presents comprehensive coverage of the theoretical and practicalaspects of WCDMA* Provides a detailed roadmap by presenting the materialstep-by-step for readers from differing backgrounds* Systematically presents the latest results in the fieldIdeal for Engineers, academics and postgraduate students involvedin research and development, engineers involved in management andadministration.
