Abstract

A new stereo echo cancellation algorithm using imaginary input-output relationships is proposed. This algorithm is based on the idea of approximating the input-output relationships for the reversed stereo signals. Unlike conventional methods, which use the input-output relationships in only one situation, our algorithm uses the simultaneous equations for the input-output relationships under two different conditions. Consequently, convergence to the unique steady-state solution is faster than with the conventional algorithm. Computer simulations using data recorded in a conference room demonstrate the effectiveness of this algorithm.
