Abstract

Abstract:

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.

Key words: TD-SCDMA, multi-carrier,, multi-carrier HSDPA
