摘要
讨论了RLS(递归最小二乘)和LMS(最小均方)自适应滤波算法及原理,对两种算法进行了系统全面的分析,对比研究了各自的优势及不足,提出了两种算法在语音消噪仿真中的算法实现,对实际语音信号进行了仿真消噪,研究表明选用算法对语音消噪是明显有效的,RLS自适应消噪算法及LMS自适应噪声抵消算法具有很强的实际应用价值。
The algorithms and principles of RLS(recursive least-squares) and LMS(least mean squares) adaptive filter are studied. The two de-noising methods are analyzed systematically and comprehensively, and comparisons of their advantages and disadvantages are presented. The simulation algorithms based on the speech de-noising is given, and the simulationon de-noising of actual speech signal with white noise is made. The research result shows that the RLS and LMS algorithms for speech de-noising are obviously effective, and the RLS and LMS adaptive filter algorithms are of great practical value.
