Practically efficient nonlinear acoustic echo cancellers using cascaded block RLS and FLMS adaptive filters

Yiteng Huang, Jan Skoglund, Alejandro Luebs

Abstract

This paper presents a practically efficient implementation for non-linear acoustic echo cancellation (NAEC). The echo path is modeled by a novel hybrid Taylor-Volterra pre-processor followed by a linear FIR filter. A cascaded block RLS and unconstrained FLMS adaptive algorithm is developed to jointly identify the pre-processor and the FIR filter. This implementation is validated via simulations.
