Open publisher page 0 citations

Abstract

By analyzing and researching the LMS algorithm of smart antenna,it is found that the traditional LMS algorithm can not solve the problem of the convergence rate and the steady-state error at the same time,that is,the permanent step factor can not solve the contradiction between the convergence rate and the steady-state error.So an improved LMS algorithm was proposed and verified by computer simulation.The application of the improved LMS algorithm efficiently solves the problem in a convergent process.
