Research and Simulation on Factors of Steepest Descent-CMA

The Steepest Descent-CMA is one of the CMA,Due to simple calculation,and has been used widely.The purpose of this paper is to find out how can these factors such as adaptive step size,the number of elements and the spacing between the elements affect the Steepest Descent-CMA.We did some basic research on the factors of the Steepest Descent-CMA by MATLAB.We proved the way the factors affect the Steepest Descent-CMA.In this wa,y the paper lays the foundation to further optimize the performance of adaptive beam forming.
