Abstract


In acoustic echo cancellation as, e.g., for mobile communication receivers, loudspeakers and their amplifiers cause significant non-linear distortion in the echo path, resulting in a degradation of the performance of linear echo cancelers. In order to cope with this type of nonlinear echo paths, we discuss a orthogonalized version power filters that can be considered as a parallelized realization of the cascade of a memoryless polynomial followed by a linear filter. As, in the echo cancellation context, the statistics of the speech input are non-stationary and not known in advance, the orthogonalization follows the signal statistics. The performance of the resulting novel nonlinear structure is evaluated by experiments using real hardware. © 2005 IEEE.
