对最陡下降恒模算法系统因素的研究与仿真

摘要

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.%最陡下降恒模算法是恒模算法的一种,由于其计算简单因而取得广泛应用.为了分析收敛因子、阵元间距、阵元个数等阵列系统因素是如何对最陡下降恒模算法产生影响.运用MATLAB仿真对最陡下降恒模算法的系统因素(既上面提到的收敛因子、阵元间距、阵元个数等系统因素)进行常规的分析与研究.并从实验数据得出这些因素能够对最陡下降恒模自适应波束形成有着明显的影响,为进一步优化自适应波束形成算法提供了一些参考.
