自适应有源噪声控制算法研究

The Study on the Algorithms of the Adaptive Noise Control

自适应有源降噪作为一种有效的降噪方法，已获得了很广泛的应用，本文主要介绍研究有源噪声控制中的ＦＬＭＳ，ＦＲＬＳ算法。其中ＦＬＭＳ具有设备简单、易行和对无色噪声良好的收敛性等特点，是一种经典的自适应算法，而ＦＲＬＳ实现起来相对要复杂些，但是其对宽带信号和有色噪声的收敛性能较ＦＬＭＳ要好得多。计算机仿真结果验证了算法的有效性。

As a useful method, the Adaptive Active Noise Control is widely applied in noise control. The typical algorithm FLMS and FRLS in AANC are studied in this paper. As we know, they are the basic methods used for adaptive calculation. They have respectable characteristics in convergence performance and complexity. The FLMS is fit for white noise and FRLS is fit for wide band and colored noise. The computer simulations are also presented.
