基于误差反馈的变步长LMS自适应滤波算法
Variable step⁃size LMS adaptive filtering algorithm based on error feedback
摘要
Abstract
By studying variable step⁃size LMS algorithms,a novel variable step⁃size LMS algorithm is proposed. The algo⁃rithm based on Sigmoid function adjusts the function parameters through the introduction of feedback of error factor and solves the problem of parameter setting in generic Sigmoid function. The algorithm has a faster convergence rate and a small steady⁃state error. Simulation results show that,compared with other algorithms,the algorithm is more perfect in convergence rate and steady⁃state error,and has a better applicability.关键词
