This paper introduces a novel approach to address the challenges of Nonlinear Acoustic Echo Cancellation (NAEC) by proposing an integration of Frequency Domain Adaptive Filters (FDAF) into a Collaborative Functional Link Adaptive Filters (CFLAF) framework. The research focuses on enhancing the robustness of the adaptive filtering system in the presence of changing linear-to-nonlinear power ratios (LNLR) over time.

This paper introduces a novel approach to address the challenges of Nonlinear Acoustic Echo Cancellation (NAEC) by proposing an integration of Frequency Domain Adaptive Filters (FDAF) into a Collaborative Functional Link Adaptive Filters (CFLAF) framework. The research focuses on enhancing the robustness of the adaptive filtering system in the presence of changing linear-to-nonlinear power ratios (LNLR) over time.
