Abstract

This paper proposes new variable regularized (VR) partial update (PU) affine projection algorithms (APAs) for distributed estimation over adaptive networks. They extend the conventional diffuse PU-APAs (Diff-PU-APAs) by imposing a regularization parameter to mitigate possible impairments, such as modeling uncertainties and lacking of excitation, and to deal with sparse channel estimation problems. In addition, the mean and mean square convergence performance of the proposed algorithms is studied, which provides convergence conditions of the proposed algorithms. The performance of the Diff-VR-PU-APAs is demonstrated by several computer simulations in distributed networks.
