This presentation focuses on cascaded approaches to non-linear acoustic echo cancellation (AEC) for mobile communications. The contributions are two-fold. They relate (i) to computationally efficient pre-processing and clipping compensation which aims to improve non-linear modelling and (ii) decorrelation filtering which aims to improve the tracking performance of a conventional linear AEC algorithm. While well-established in the literature the two modules require significant development in order that they function coherently in a cascaded approach. This paper presents new, adaptive parameterisation procedures for both modules and demonstrates significant improvements in terms of echo return loss enhancement when the two modules are combined.
