Abstract

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
