A family of variable step-size affine projection adaptive filtering algorithms with selevtive partial update

Abstract

This paper presents a family variable step-size (VSS) affine projection (AP) adaptive filtering algorithms with selective partial updates (SPU). The presented algorithms have good convergence speed, low steady state mean square error (MSE), and low computational complexity features. We demonstrate the good performance of the proposed algorithms through simulations in system identification and acoustic echo cancellation scenarios.
