| Abstract |
This paper proposes an affine projection algorithm (APA) that determines its projection order using a pseudo-fractional method. The pseudo-fractional method adjusts the projection order by comparing the averages of the accumulated squared errors. The method relaxes the constraint of the conventional APA that the projection order must be integral, and it includes both the integral projection order and the fractional projection order. Simulation results show that the proposed algorithm achieves a faster convergence rate and a smaller steady-state estimation error than the existing algorithms. |
