基于LMS算法的天线波束方向图仿真研究

内容简介：最小均方（LMS）算法是一种常用的天线波束形成算法。本文首先对 LMS 算法的一般原理进行了研究，然后对LMS算法进行了改进，将固定步长改为变步长，最后应用Matlab对算法进行了仿真。仿真结果表明改进的LMS算法具有良好的效果，收敛速度比经典LMS算法更快，对天线性能有一定的提高。

Abstract：The least mean-square (LMS) algorithm is a widely used antenna beam pattern algorithm. In this paper, the principle of the LMS algorithm is presented first, then the LMS algorithm is improved and the fixed step is replaced by a variety step. Finally, the algorithm is simulated based on Matlab. The simulation results show that the effect of the improved algorithm is well. It has a faster convergence speed, and it can improve the capability of the antenna.
