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 an effective noise reduction method, adaptive active noise reduction has been widely used. This paper mainly introduces the research of FLMS and FRLS algorithms in active noise control. Among them, FLMS is a classical adaptive algorithm which is simple and easy to operate and has good convergence to colorless noise. However, FRLS is relatively complicated to implement, but its convergence performance to broadband signals and colored noise FLMS is much better. Computer simulation results verify the effectiveness of the algorithm.
