摘要： 对智能天线中的自适应波束成形算法进行研究，并利用Matlab软件对固定步长和变步长两种LMS算法进行计算机仿真实验。仿真结果表明，变步长的LMS算法均方误差收敛效果较好，波束形成对干扰信号的抑制更加精确，有较强的实用性。

Abstract: This paper researches on adaptive beamforming algorithm based on smart antenna, both of fixed step and variable step size belongs to LMS, and they are simulated with computer in simulated channels by Natlab. The simulated results indicate that the mean square error of variable step LMS algorithm has better convergence effects, and beamforming makes suppression of disturbance signal more accurately. It is proved to be effective.
Key words: smart antenna, LMS, beamforming, Matlab, variable step-size
