N2 - The normalized subband adaptive filtering algorithm can improve the convergence rate of the normalized least mean square algorithm when dealing with the correlated input signals, but it is plagued by a slow convergence issue in the stable noise. For that reason, the normalized subband p-norm (NSPN) algorithm based on the mean p-power error criterion is proposed in this paper, which shows a fast convergence rate in the α-stable noise. Moreover, by taking advantage of the tap-weights feedback-based convex combination (TFC) scheme, we propose the TFC based NSPN algorithm, which further reaches low steady-state misadjustment under fast convergence. Simulation results have confirmed the superior performance of the proposed algorithms in both system identification and acoustic echo cancellation scenarios.
