摘要
在移动通信中,多径信号的分组一直是研究的重点.本文提出一种多径环境下的宿主用户和多径信号的分组和DOA估计算法.该算法不需要采用扩频技术确定多径信号的归属问题,因此不但可以应用于CDMA系统,而且可以应用于GSM系统.
In mobile communication systems, the work upon grouping multipath signal is very important always. An algorithm is proposed which firstly separates user signals and multipath signals in system, then estimates DOA of them. Because this algorithm does not need spread spectrum to identify multipath signals, it not only can be adopted in CDMA system, but also can be applied to GSM system.
