摘　　要：通过对现有小区搜索PSS定时同步算法的研究,结合Zadoff-Chu序列自身的特性,给出了一种低复杂度的PSS定时同步算法的实现方案。理论分析和仿真结果表明,该方案能够简化PSS定时同步的计算复杂度,具有高效性、可行性,能够满足TD-LTE系统小区搜索的性能要求。Researching on cell search PSS timing synchronization algorithm,and according to the Zadoff-Chu sequence charac- ter, a low-complexity implementation approach is proposed in this paper. Both the theory analysis and simulation results show that the algorithm proposed can reduce computational complexity and it is feasible and efficient, which satisfies the performance require- ments on cell search in TD-LTE system.
