A New Strategy of Adaptive Nonlinear Echo Cancelling Volterra-Wiener Filter Structure Selection

摘要

In the article a nonlinear orthogonal echo cancelling filter parameters selection strategy is proposed to maximize echo cancelling quality to computation complexity ratio. Presented approach leads to the orthogonal realization of the nonlinear echo cancelling filter of Volterra-Wiener class which structure changes due to higher-order statistics of the filtered signals.
