摘　　要：基于递归最小二乘(RLS)自适应滤波理论,本文提出了一种天线阵列的幅度和相位不一致性的有源在线 校正方法。该方法具有快速稳健的收敛性能,不受天线阵列的几何形式限制,也适用于移动用户数大于阵元数的实际通信 环境中。计算机仿真证实了该方法的有效性。The unknown amplitude and phase errors of the responses of the antenna array will degrade the performance of a smart antenna system seriously. Based on the recursive least square （RLS） adaptive filter theory, an online calibration algorithm with an auxiliary signal source is presented in this paper. The algorithm can be applied to the non-uniform array where the number of users is greater than the number of antennas, and the fast and robust convergence can be ensured as well. Computer simulation demonstrates that it is effective.
