AN AFFINE PROJECTION ALGORITHM WITH VARIABLE PROJECTION ORDER BASED ON MEAN-SQUARE DEVIATION ANALYSIS

摘要

We present an affine projection algorithm (APA) thatrnautomatically determines projection order in order tornimprove convergence performance. Determination of thernprojection order is achieved by mean-square deviationrn(MSD) analysis. The projection order of the proposedrnalgorithm varies in accordance with the steady-state MSD.rnExperimental results indicate that the proposed algorithmrnhas a faster convergence rate and a smaller misalignmentrnthan the existing affine projection algorithms with variablernprojection order.
