摘　　要：介绍一种改进的算法在噪声消除中的应用。算法利用第二级滤波器估计期望信号,然后在第一级滤波器中消除期望信号对算法误差的影响。仿真表明算法可以明显地降低算法的均方误差,得到很好的输出性能。This paper introduces a modified LMS algorithrn which is used in noise cancellation. The algorithm utilizes the secondary filter to estimate the desired signal and then counteracts the affection of the desired signal to the first filter. Through analysis and simulation, the obtained results show that it can obviously reduce the square error and obtain good output performance.
