摘要
文中提供了一种适于TD-SCDMA系统基站间帧同步的差分技术实现方法,所述帧同步的方法主要是利用接受信号和基站间传输的同步序列(SYNC_DL码和Midamble码)之间的相关性来实现同步。相关性处理是在NF个连续的无线帧基础上进行的同步性能测试,试验结果证明利用一个同步序列(仅用SYNC码[3])的相关性的方法,能够非常有效的实现帧同步。
In this paper, a method to realize the On-Air frame synchronization between two BSs is proposed. The main operation performed in the proposed frame synchronization procedure is the correlation between the received signal and the known synchronization sequences transmitted in the frame by each BS, respectively the SYNC code（SYNC_DL code） and the training sequence code（Midamble code）. The correlation process is repeated on a chosen number NF of consecutive radio frames in order to obtain better synchronization performance. The method presented in these pages allows to have a higher reliability and accuracy with respect to the on-air synchronization methods described in the UTRAN standard for TDD-LCR , where the procedure is performed by using the correlation with one synchronization sequence only （i.e. SYNC code）.
