Fig. 10From: Significance-aware filtering for nonlinear acoustic echo cancellation a–b ERLE performance of the novel ESA-HM and a PBSA-HGM in comparison to a classical PB-HGM and a linear model, adapted by an FNLMS. Note that the PB-HGM, PBSA-HGM, and ESA-HM have about 3.60, 2.33, and 2.17 times the complexity of a linear filter, respectivelyBack to article page
