IEICE technical report   110(471) 7-12   Mar 2011
An acoustic echo canceler (AEC) has been used to remove acoustic echoes generated in hands-free telecommunications. The AEC cancels the acoustic echoes by approximating the echo-path with use of an adaptive filter and subtracting the pseudo echoes...

IEICE technical report   105(658) 91-96   Mar 2006
In this report, we present a structure of blind source separation which is for the reduction of double talk influence on the echo canceller. The descpription of the report involve the problem of double talk, the way to reduce the double talk probl...
