Abstract

The fundamental problems of stereophonic acoustic echo cancellation were discussed and the recent solutions were reviewed. The stereo echo cancellation was achieved by linearly combining two monoaural echo cancellers. A duofilter control system including a continually running adaptive filter and a fixed filter was used for double talk control. A second order stereo projection algorithm was used in the adaptive filter and a stereo switch was also implemented.
