In this paper, we propose an error estimate algorithm (EEA) for stereophonic acoustic echo cancellation (SAEC) that is based on an extension of the set-membership normalized least mean-squares (SM-NLMS) algorithm combined with the affine projection (AP) algorithm. In the EEA, with the minimum error signal fixed, we compute the filter lengths so that the(More)
Echo is the time delayed version of the original signal. Acoustic echo results from a feedback path set up between the speaker and the microphone in a mobile phone, hands-free phone .Echo can degrade the quality of service in telecommunication. Therefore echo cancellation is an important part of communication systems. A new approach based on the number of(More)
