Abstract

En 中文

Affine projection (AP) algorithm has been widely used in many applications because of the fast convergence ability for colored inputs. To reduce high steady-state errors resulting from weight-noise correlations, this letter presents an interval-extraction mechanism for AP algorithm, named IEAP. In the procedure, we recommend using an interval between each data point of the output vector in the AP update. Finally, by means of theoretical mean square deviations analysis and computer simulations, the interval-extraction method is demonstrated to be effective.
