Abstract

Acoustic echo is a common phenomenon in voice communication. The interference signal caused by acoustic echo will greatly reduce the quality of voice transmission. Thus, techniques should be applied to diminish acoustic echo. This paper endeavors to introduce the application of adaptive filter in acoustic echo cancellation. Adaptive filter can dynamically adapt its parameters to minimize the difference between its output and the actual echo signal so that the actual echo signal can be eliminated as much as possible. Furthermore, this paper elaborates the operational process of certain common filtering algorithms of adaptive filter and performs comparison of the performance of these filtering algorithms.
