We studied the performances of this system by simulations, including the impacts of channel fading, angle spread and co-channel interference on DOA estimation.

通过仿真，研究了这一系统在移动通信环境下的性能，包括信道衰落、信号角度扩散及同频干扰用户等对DOA估计的影响。

In cellular systems, transmitter power must be controlled in order to reduce the co-channel interference caused by frequency reuse.

在蜂窝通信系统中，为了减小由于频率复用造成的共信道干扰，必须对用户的发送功率进行控制。
