Abstract

An improved design of acoustic echo canceller has been proposed for the advancement in telecommunication to avoid acoustic echo, which is capable of providing convincing results. In this acoustic echo cancellation algorithm, a Frequency-Domain Adaptive Filter (FDAF) has been considered which uses a fast convolution technique to compute the output signal and filter updates. This computation executes quickly in MATLAB through frequency-bin step size normalization to get better performance. There are different techniques already used for signal processing but the proposed design provides an advance feature for better quality signal. Since there has been a revolution in the field of personal computers in recent years, this work attempts to implement the acoustic echo canceller algorithm on a PC with the help
of the MATLAB software.
