基于ＣＤＭＡ的第三代移动无线通信系统（下）ＡｌｆｒｅｄＢａｉｅｒ等３蜂窝区３．１同步实际数据和控制信道使用长ＰＮ码异步直接序列扩展，导致信道间和蜂窝小区间同步要求不严格。通过导频信道和同步信道与基站同步的移动台，可以直接统调该处的发射ＣＤＭＡ帧与接收...
Third generation of mobile wireless communication system based on CDMA (below) AlfredBaier et al. 3 Cellular 3.1 Synchronization The actual data and control channel use long PN sequence to be asynchronous direct sequence extension, resulting in less stringent inter-channel and cell-to-cell synchronization requirements. The mobile station synchronized with the base station through the pilot channel and the synchronization channel can directly modulate the transmitted CDMA frame and receive ...
