Abstract :
A subband adaptive filter normalized least mean fourth criterion algorithm is proposed in which the fourth-order moments of subband error signals are minimized as cost functions. Simulation results verify that the proposed algorithm has a higher convergence rate than a conventional normalized subband adaptive filter algorithm in a non-Gaussian noise environment and for colored input signals.
