摘　　要：基于最小均方(LMS)自适应滤波原理,该文提出了两种天线阵列的有源在线校正算法.这些算法不依赖于天线阵列的几何形式,可适用于移动用户数大于阵元数的实际通信环境中.计算机仿真证实了算法的有效性.Based on the Least Mean Squares (LMS) principle, an online calibration algorithm with an auxiliary signal source is presented, and its improved algorithm is also given. These algorithms can be applied to the non-uniform array, and to the number of user greater than the number of antenna as well. Computer simulation demonstrates that they are effective.
