| 摘 要： | 小区搜索的目的是要保证UE获得系统的时间同步和频率同步,从而能读取系统信息和进行后续的数据传输。本文介绍TDD-LTE小区搜索的算法和步骤,在一定性能的前提保证下完成小区搜索,使得UE解析出小区的ID,这个小区ID对应LTE系统中504种小区的标识。其算法主要分为三步：主同步信号（PSS）同步、辅同步信号（SSS）同步和频偏估计（FOE）。最后仿真了各个步骤的性能。

| Abstract: | The Aim of cell search is to obtain the time and frequency synchronization of the system,and then UE get system information block and later data transportation.This paper mainly describe the cell search algorithm of the TDD LTE systems,UE decode the Cell ID after cell search.The algorithm can be divided into 3 sub-processes: Prime Synchronization Signal(PSS) synchronization,Secondary Synchronization Signal(SSS) synchronization and frequency offset estimation(FOE).At last,the performance is simulated. |
