Abstract :
The authors had proposed a stereophonic echo canceller for correct echo path estimation. We pay attention to the convergence value of the filter coefficient vector of the multichannel least mean squares (MC-LMS) and that of the compact multichannel echo canceller (CEC) and use those differences. Concretely, the coefficient vector of the MC-LMS is converged to a correct echo-path by properly substituting a part of the coefficient vector of the CEC for that of the MC-LMS. We show by simulation for the white noise input that the coefficient vector of the proposed method converges to the correct echo-path
