SA-HGM for efficient nonlinear system identification: the temporal support modeled by the filters is color-coded by the squares below the IR symbols h . White squares indicate unmodeled temporal support and red and blue squares represent modeled support corresponding to the direct path and the complementary region, respectively. Typically, \(\hat {y}_{\text {SA}}\)(k) is employed as final echo estimate
