Stereophonic acoustic echo cancellation (AEC) is typically intended for use in high quality teleconferencing systems and multiparticipant desktop conferencing that implement sound transmission through two channels. Because of the high correlation between the two channel signals, rapidly converging adaptive filter algorithms (such as the two-channel fast recursive least-squares -FRLS) are required. In this paper, we propose a new and efficient frequency domain adaptive algorithm that achieves
