说明：  在LTE系统中，为了接入网络，用户设备要检测主同步信号和辅同步信号。这篇文章提出了一个新颖的接入LTE系统的方法。
(In LTE system, in order to access the network,user equipment (UE) should detect the primary synchronization signal (PSS) and secondary synchronization signal (SSS) in downlink (DL) signal from the surrounding base stations (BS). This paper presents a novel initial cell search (ICS) scheme in TD-LTE system that contains two steps.)
