Abstract : Acoustic echo cancellation is an essential signal enhancement tool in hands-free communication. Acoustic echo is caused due to leakage from the loudspeaker to the microphone in settings like hands free telephony. Nowadays, adaptive filtering techniques are generally being implemented to suppress this echo. This paper discusses various variable step-size NLMS based algorithms which can be implemented in acoustic echo cancelling applications. Simulation results using real audio recordings in a room demonstrate that GSER algorithm have the best performance in real time environment. The performance of these algorithms in terms of ERLE and NSEC curves are obtained and comparison between them is done. Also a simple Double-Talk Detection scheme is proposed in this paper.
