Acoustic Echo Cancellation For Speech And Random Signal Using Estimated Impulse Responses

In this paper, the Acoustic Echo Cancellation (AEC) are investigated by using Finite Impulse Responses Adaptive Filter with the analysis of Mean Square Error (MSE) and its convergence property. It is the result of a project in the course Fundamental of Signal Processing at Chongqing University of Posts and Telecommunications. It focuses on Normalized Least Mean Square (NLMS) algorithm of adaptive filtering, employing a discrete signal processing in MATLAB for simulation with speech and random signals. Keywords— AEC, Adaptive Filter, MSE, LMS, NLMS
