- Abstract
- In this paper, a new nonlinear acoustic echo cancellation system is proposed, which utilizes adaptive 3rd-order Volterra filtering with a modified variable step-size GSPAP (VSS-GSPAP) algorithm. In particular, the proposed approach yields better echo cancellation performance than conventional VSS-NLMS methods in case of the double-talk situation in background noise. Simulation results demonstrate that, in addition to better AEC performance, the proposed one also yields faster convergence than the conventional VSS-NLMS.
