A Novel Adaptive method for Acoustic Echo Cancellation

Abstract

Speech is compulsory in audio teleconferenceing system. In present scenareo acoustic echo is a major setback for user and causes a lessening in the quality of the communication.By means of some adaptive filtering methods acoustic echo canbe eliminated and can be reachrd in a desired value. A detail performance assessment is reported, including echo return loss enhancement (ERLE), convergence time and system distance metrics.We have also compared two different signals and how noise can be cancelled out using NLMS algorithm.
