Orthogonal Schur-Type Solution of the Nonlinear Echo-Cancelling Problem
Paweł Biernacki · 2007
In this article a new method of the linear and nonlinear echo reduction is presented. Geometric recursive solution of the nonlinear optimal (in the least-squares sense) echo cancelling problem is proposed. Presented approach leads to the orthogonal realization of the nonlinear echo cancelling filter of the Volterra-Wiener class.
