Affine projection algorithm using regressive estimated error (Q542665)

Summary: An affine projection algorithm using regressive estimated error (APA-REE) is presented in this paper. By redefining the iterated error of the affine projection algorithm (APA), a new algorithm is obtained, and it improves the adaptive filtering convergence rate. We analyze the iterated error signal and the stability for the APA-REE algorithm. The steady-state weights of the APA-REE algorithm are proved to be unbiased and consistent. The simulation results show that the proposed algorithm has a fast convergence rate compared with the APA algorithm.
