基于对ＬＭＳ算法的研究，提出一种适用于自适应噪声对消（ＡＮＣ）系统的ＥＬＭＳ算法结构，分析比较了ＥＬＭＳ算法与ＬＭＳ算法的统计性能，还提出了一种较为实用的变步长归一化ＭＶＳ－ＡＮＥＬＭＳ算法．大量的计算机模拟仿真论证了新算法的优越性．
Based on the research of LMS algorithm, an ELMS algorithm structure for adaptive noise cancellation (ANC) system is proposed. The statistical performance of ELMS algorithm and LMS algorithm is analyzed and compared. A more practical variable step size A MVS-ANELMS algorithm. A large number of computer simulation demonstrate the superiority of the new algorithm.
