The performance of the adaptive algorithm can directly affect the effect of the echo canceller. 自适应算法的性能直接影响着回波消除器的效果。
This text will introduce the principles and implementation of echo canceller, and the tradeoff between the performance and the cost. 本文将介绍回音消除器的原理及其实作方法，并考量到如何在效能与有限资源之间，取得一个可接受的平衡点。
