An Affine Projection Algorithm with Variable Projection Order using the MSE Criterion.

This paper proposes an affine projection algorithm (APA) with variable projection order using the mean-square error (MSE) criterion. The proposed algorithm determines the projection order at every iteration to use it in the update equation of the proposed APA. The MSE criterion is employed to decide the projection order reasonably. Moreover, this algorithm checks the steady-state condition to change the MSE criterion for improving the performance of APA. The experimental results show that the proposed algorithm achieves faster convergence rate, smaller steady-state estimation error and lower computational complexity than the existing APAs.
