摘要

本文对最小均方算法(LMS)和样本矩阵反演算法(SMI)在智能天线优化中的应用进行了比较研究。通过改变LMS和SMI算法的不同参数，研究了它们在波束形成和零转向问题中的性能。零转向以及多个干扰信号也完成。比较了两种算法的零深度、多重干扰、最大旁瓣电平和收敛速度。

A comparative study of beamforming techniques using LMS and SMI algorithms in smart antennas

This paper, we presents a comparative study between the Least Mean Square (LMS) and Sample Matrix Inversion (SMI) algorithms and their application to the smart antenna optimization. The performance of the LMS and SMI algorithms is studied by varying its different parameters in beamforming and null steering problems. Null steering along with multiple interference signals is also done. The two algorithms are compared for null depth, multiple interference, maximum sidelobe level and rate of convergence.
