| 摘 要： | 介绍了一种基于RLS算法的自适应噪声对消系统,说明了噪声对消系统的原理以及RLS算法的步骤与流程。通过实例仿真,得到了基于RLS算法的自适应噪声抵消系统仿真图。分析仿真结果得出,在单频干扰与宽带噪声干扰两种情况下,RLS自适应滤波器都能很好地消除干扰得到有用信号。证实了在通信语音信号处理中,用基于RLS算法的自适应噪声对消系统可以消除语音噪声,提高语音通信的信号质量。

| Abstract: | Introduce the theory of the adaptive noise canceling system based on RLS algorithm,and also present the computer simulation results.The simulation results indicate that the RLS adaptive noise canceling system can cancel single and broad band frequency interferential.So it can be used to cancel the noise involved in the sound to improve signal quality in the communication signal processing. |
