TD-SCDMA直放站中的基带同步技术
首发时间:2008-09-04
摘要:由于TD-SCDMA系统为时分复用系统,和传统的FDD不同,其需要解决其在时间上的同步问题,文中对TD-SCDMA直放站中的同步技术进行了分析与研究,着重分析了三种同步方式中的基带解码同步方式.并研究了TD-SCDMA直放站同步码获取理论算法,对其在MATLAB中进行了理论仿真,验证了同步码获取算法的正确性。

Base-band synchronization technology in TD-SCDMA repeater
Abstract:Because of the TDD system,not the FDD, td-scdma must solve the synchronization problem, this paper analyses and researches the synchronization technology about the TD-SCDMA repeater, especially analyses the base-band demodulation synchronization style in three synchronization ways in details. Meanwhile, this paper researches the TD-SCDMA repeater base-band synchronization theoretic arithmetic, makes the theoretic simulation on the Matlab software environment based on it, and validates its correctness.
Keywords: TD-SCDMA repeater base-band synchronization SYNC_DL switch
