Abstract 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.
