Proposed novel ESA-HM for efficient nonlinear system identification: estimating an equalizing RIR \(\hat {h}_{\text {eq},l}\) (k) to obtain an estimate \(\hat {x}_{\text {NL}}\)(k) of the nonlinearly distorted loudspeaker signal (block γ) allows to assess the nonlinear distortions by a very short HGM (block β), which in turn is used to estimate the preprocessor of the HM modeling the acoustic echo path (block α)
