摘　　要：为了提高TD-SCDMA系统的传输速率和系统容量,更好地支持高速数据业务及大规模组网能力,TD-SCDMA开始向多载波方向进行增强和演进。本文首先介绍了TD-SCDMA未来演进和发展趋势,提出了TD-SCDMA演进的四阶段;然后重点讨论了多载波TD-SCDMA技术特征,分别对不引入HSDPA的多载波TD-SCDMA和引入HSDPA的多载波TD-SCDMA进行了介绍,并对多载波TD-SCDMA系统的容量和性能进行了评估;最后总结了多载波TD-SCDMA技术的未来挑战。In order to improve the transmission rate and capacity of TD-SCDMA, and to support high data rate services as well as buildup network in large scale area, the evolution of TD-SCDMA happens toward the multi-carrier. This paper proposed the evolution and enhanced map of TD-SCDMA, in which there are four evolution phases. Meanwhile, the multi-carrier techniques of TD-SCDMA, including both the multi-carrier TD-SCDMA and multi-carrier TD-SCDMA HSDPA, are analyzed and discussed. The performance evaluation and the protocol modification due to the involvements of multi-carrier techniques are presented. The challenges and future development of multi-carrier techniques for TD-SCDMA systems are discussed.
