Abstract

In this paper, an application of the blind signal separation circuit for the purpose of the reduction in double-talk failure in the echo canceller is explained. An examination of the double-talk problem in the echo canceller, and the constitution method which reduces it by blind signal separation circuit, and the characteristic improvement of blind signal separation circuit is described. We discuss in this paper an alternative algorithm in which an auxiliary term is added for improving the convergence rate.
