变步长动量常数模算法
Variable step-size momentum constant module algorithm
摘要
Abstract
In order to solve the conflict between steady-state error and convergence speed in CMA algorithm , this paper discusses a variable step-size momentum algorithm w hich brings the momentum term and variable step-size into CM A algorithm . In new algorithm , steady-state error and step-size together effect current step-size , considering the influence of momentum term when weights vector updating . Simulation results show that compared with the original algorithm , the proposed algorithm can improve the convergence rate and reduce the steady-state error .关键词
