摘　　要：基于相干检测和使用部分相关的非相干检测,提出了一种适用于TD-LTE系统下行辅同步信号SSS(Secondary Synchronization Signal)的检测方法。根据SSS索引号(m0,m1)对应关系,通过优化降低了索引号m1的检测运算量。仿真结果表明,在不同的信道环境下,本文提出的SSS检测方法能较好地工作,具有稳定、检测复杂度低等优点。On the basis of coherent detection and non-coherent detection using partial correlation, a novel method of secondary synchronization signal（SSS） detection algorithm in TD-LTE system downlink is proposed in this paper. According to the relationship between mO and ml of SSS index, the detection complexity of index ml is reduced through optimization. Simulation results show the effectiveness and low complexity of SSS detection algorithm under scenarios with different channel environment.
