LMS2算法收敛步长的分析求解

ANALYSIS AND SOLUTION OF CONVERGENCE STEP-SIZE FOR LMS2 ALGORITHM

本文从ＬＭＳ２失调的准确表达式出发，导出了在小失调情况下计算步长的公式，计算机模拟结果表明，按本文方法计算步长可获得满意的失调量。

A formula to calculate the step-size of LMS2 algorithm is derived based on ex-act expression of the misadjustment, the simulated result by computer shows that mis-adjustment pleased is achieved by adopting the method presented in this paper for calculat-ing the algorithm step-size.
