摘要

同信道干扰干扰蜂窝无线电系统的频谱效率。提出了一种基于恒模算法(CMA)的自适应阵列天线同信道干扰抑制方法。当我们采用自适应阵列天线来减少同信道干扰时，可能会捕获到同信道干扰信号。该方法在接收到的信号中产生干扰信号的副本，然后将其消除，从而获得所需的信号。GMSK调制的计算机仿真结果表明，采用该方法的CMA自适应阵列天线比传统的CMA自适应阵列天线更能减少同信道干扰。

Co-channel interference reduction method using CMA adaptive array antenna

Co-channel interference disturbs the spectral efficiency in cellular radio systems. A co-channel interference reduction method using a constant modulus algorithm (CMA) adaptive array antenna is proposed. When we apply an adaptive array antenna to reduce co-channel interference, a co-channel interference signal may be captured. In this method, the replica of the interference signal is generated and then eliminated from the received signal, and thus the desired signal can be obtained. Computer simulation results of GMSK modulation confirm that a CMA adaptive array antenna that uses this method can reduce co-channel interference more than a conventional CMA adaptive array antenna.
