一种用于回声抵消的快速频域自适应滤波算法的实现
Fast Algorithm in Frequency Domain for Adaptive Filter in AEC
声学回声抵消(AEC)是决定网络电话和视频会议系统中通话清晰度的关键因素，因此是网络电话系统中必不可少的部分，回声抵消的核心是自适应滤波器。本文介绍了声学回声抵消的基本原理以及一种在回声抵消中表现优良的多延迟频域分块自适应滤波器（MDF）的算法及其实现方法。
coustic echo canceller (AEC) is an important device in the system of video conference and IP telephone. Adaptive filter, as the core of echo canceller, has many algorithms. The multi-delay block frequency-domain (MDF) adaptive filter is an excellent candidate for both acoustic and network echo cancellation. This paper presents this algorithm detailedly .
