Abstract :
An equation-error adaptive infinite-impulse response (IIR) filtering method has slow convergence rate when the input signal is correlated. To overcome this problem, we present a new equation-error adaptive IIR filtering method based on data reuse. We also provide the corresponding debiasing solution for the proposed algorithm. Experimental result demonstrates that the proposed algorithm has much faster convergence rate than the conventional one.
