Abstract

Acoustic echo cancellation is common in voice communication. The interference signal caused by acoustic echo will reduce the quality of voice transmission. The current paper discusses the cause and technique for cancellation of acoustic echo, mostly based on the use of adaptive filter. Adaptive filter iteratively alters its parameters to minimize the difference between its output and the actual signal. Morever, this paper makes a comparison of various adaptive filtering algorithms and elaborates the detailed operational process of NLMS filtering algorithm.
