摘要
提出了变阶自适应滤波器和一种变步长变阶自适应 L MS算法。通过仿真证明合适选取参数 ,该算法比单一变步长算法要优越 ,变步长变阶自适应滤波器同时具有变步长定低阶滤波器和变步长定高阶滤波器的优点。
An adaptive filter with variable weight length and a LMS algorithm of variable step size and variable weight length are presented.It′s confirmed by the computer simulation that this algorithms is better than the common algorithms of variable step size. As compared with common algorithms of variable step size, it has the advantages of the high ranks adaptive filters and low ranks adaptive filters.
