In the paper, a kind of adaptive noise cancellation filter with reference channel based on Least Mean Square (LMS) algorithm is discussed.
本文讨论了一种带有参考通道的自适应话音消噪滤波器原理，该滤波器采用最小均方差(LMS)算法。
The adaptive filter and its least mean square (LMS) algorithm are reviewed. Computer simulation tests were made and results obtained therefrom are discussed.
本文介绍了自适应滤波器及其最小均方(LMS)算法，通过计算机进行了仿真实验并对仿真结果进行了讨论。
Though the decision directed least mean square error algorithm (DD-LMS) has small residual error, when the channel eye close, it can not converge. That is, it has no cold start ability.
虽然判决导引最小均方误差算法(DD - LMS)剩余误差小，但是，在信道眼图闭合的情况下，该算法无法收敛，即不具备冷启动能力。
