“…Despite these challenges, single-channel linear AEC has already reached a mature state as vital part of modern communication *Correspondence: huemmer@lnt.de Multimedia Communications and Signal Processing, University of Erlangen-Nuremberg, Cauerstraße 7, Erlangen, Germany devices. On the other hand, the nonlinear distortions created by amplifiers and transducers in miniaturized loudspeakers require dedicated nonlinear echo-path models and are still a very active research topic [8,9]. In this context, a variety of concepts for nonlinear AEC have been proposed based on artificial neural networks [10,11], Volterra filters [12,13], or Kernel methods [14,15].…”
