Summary:
We propose a convex combination of affine projection algorithm (APA) filters with individual regularization. Two APA filters with different regularization are adapted independently in order to keep the advantages of both component filters. By using their own error signals, separate filters are independently adapted, while the combination is adjusted by means of a stochastic gradient rule so as to minimize the error of the overall filter. This novel scheme provides improvement of performance in term of the convergence rate and the steady-state error. Experimental results in channel identification show the validity of the proposed algorithm when compared to the APA.
