摘要
在TD-SCDMA网络建设初期,直放站将是实现覆盖的重要补充。本文结合TD-SCDMA移动通信系统的网络特性,通过对TD-SCDMA系统帧结构的分析,探讨了TD-SCDMA系统中直放站的时序同步的重要性及几种主流的实现同步的方法,并对这几种实现方法的优缺点进行了比较。
At the early construction stage of TD-SCDMA network, a repeater is an important compensation to realize the covering area. The paper introduces the working principles of repeater in TD-SCDMA, concerning its network characteristics. Through analysis on the frame structure of TD-SCDMA, the paper also discusses the importance of time synchronization of the repeater in TD-SCDMA and several principal realizing methods used. A comparison among these methods is stated at the end of the paper.
