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...
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...

We have proposed the adaptive filter combined with the blind source separation circuit which improve the performance of echo cancelation at presence of speech signal. In this report, we present the convergence speed and the statical performance of...
