Analysis of a proposed third generation (3G) mobile communication standard, time division-synchronous code division mulitple access (TD-SCDMA)

摘要

With a growing number of consumers utilizing the Internet, companies have foreseen a consumer demand for high-speed wireless access. Since current mobile cellular systems can transfer at most 115.2 kbps per user, a third generation of mobile cellular service has been under development by various organizations since 1997. This new generation of technology will support data rates up to 2 Mbps for stationary mobiles and up to 144 kbps for vehicular traffic. This thesis focuses mainly on TD-SCDMA, one of many candidates submitted to the International Telecommunications Union for third generation review. The standard, developed in China by the Chinese Academy of Telecommunications Technology, employs both code-division multiple access and time-division duplexing to support both forward and reverse transmissions on one physical layer. This aspect, along with other common features of TD-SCDMA, will be studied and evaluated to determine if this new technology is a viable option for future commercial or military deployment.
