摘要
通过分析变步长自适应滤波算法,建立步长和误差信号之间的非线性关系,提出一种新的变步长LMS自适应滤波算法,并用计算机进行仿真,结果表明该算法在误差接近于零时步长具有缓慢变化的特性,滤波效果更好。
This paper established the non-linear relationship between the step and the error signal based on analyzing the variable step-size adaptive filter algorithm.And a new variable step size LMS adaptive filtering algorithm has been proposed.The simulation results show that the algorithm is close to zero in the error step with the characteristics of a slow change,also the results of filtering is batter.
