Description: 阐述了自适应噪声抵消(ANC)技术的基本原理,基于自适应滤波器的原理,设计了自适应噪声抵消器 在对自适应滤波器相关理论研究的基础上,重点研究了自适应噪声抵消器的核心———LMS自适应滤波算法。在MATLAB中的Simulink下,建立了自适应噪声抵消器的模型,并通过设置不同的参数进行仿真,结果表明系统能够有效地从噪声中恢复出原始信号。最后对系统进行了性能分析,给出了自适应噪声抵消系统在实际应用中选取参考信号的要求
-This paper elaborated the basic theory of Adaptive noise cancellation technology
(ANC),designed Adaptive noise canceller based on adaptive filter After studying the related
theory of adaptive filter,the core of adaptive noise canceller-LMS adaptive filtering algorithm is
researched emphatically.Under the Simulink of MATLAB,built the model of adaptive noise
canceller and simulated through installing different parameters.The results declared the system
can recover original signal from noise effectively.Finally,analyzed the function of system,and
given the system requirements of selected reference signals in the practical application.

Description: webrtc 的回声抵消(aec、aecm)算法主要包括以下几个重要模块：1.回声时延估计 2.NLMS(归一化最小均方自适应算法) 3.NLP（非线性滤波） 4.CNG(舒适噪声产生），一般经典aec算法还应包括双端检测(DT)。考虑到webrtc使用的NLMS、NLP和CNG都属于经典算法范畴，故只做简略介绍，本文重点介绍webrtc的回声时延估计算法,这也是webrtc回声抵消算法区别一般算法(如视频会议中的算法)比较有特色的地方。-webrtc echo canceller (aec, aecm) algorithm includes the following important modules: 1 echo delay estimation 2.NLMS (normalized least mean square adaptive algorithm) 3.NLP (nonlinear filtering) 4.CNG ( comfort noise generation), usually classical aec algorithm should also include double end detector (DT). Taking into account the NLMS webrtc use, NLP and CNG belong to the category of classical algorithms, it is only a brief introduction, this article focuses on the echo time delay estimation algorithm webrtc, which is the difference between general webrtc echo cancellation algorithm algorithm (such as video conferencing in the algorithm) compare interesting places.
