A Robust Fast LMM/Newton Algorithm for Generalized Side-lobe Canceller

For the conventional generalized side-lobe canceller (GSC), least square (LS) type adaptive filters have poor convergence performance when the speech enhancement system is corrupted by impulsive noise. In this paper, a robust GSC algorithm based on Fast-LMM/Newton algorithm is proposed. Experiments on dual-microphone system proved the proposed algorithm can achieve better robustness performance under the impulsive noise.
