在蜂窝系统中，移动站台必须能够进行初始同步和搜索基站来开始下行接入。这个过程被称为初始小区搜索。在这篇文章中，同步和小区搜索被具体化。一个新颖的主同步信号的算法，包括理论分析和推导展现出来。-In cellular communication systems the mobile station (MS) must be able to perform initial synchronization and search for a base station to set up

the downlink access. This process is called the initial cell search.In this paper all the procedures of synchronization and initial cell search are specified. An innovative

processing algorithm for PSS, including the theoretical

analysis and deduction, is provided. Most important of all, the proposed scheme is able to evaluate the integer

carrier frequency offset (ICFO) more accurately and improve the detection error rate effectively.
