Selective Partial Update Adaptive Filtering Algorithms for Block-Sparse System Identification

A Family of Selective Partial Update Affine Projection Adaptive Filtering Algorithms

In this paper we present a general formalism for the establishment of the family of selective partial update affine projection algorithms (SPU-APA). The SPU-APA, the SPU regularized APA (SPU-R-APA), the SPU partial rank algorithm (SPU-PRA), the SPU binormalized data reusing least mean squares (SPU-BNDR-LMS), and the SPU normalized LMS with orthogonal correction factors (SPU-NLMS-OCF) algorithms...

Partial-Update L∞-Norm Adaptive Filtering Algorithm with Sparse Updates

This paper provides a partial-update normalized sign least-mean square (NSLMS) algorithm with sparse updates. The proposed algorithm reduces the computational complexity compared with the conventional L∞-norm adaptive filtering algorithms by decreasing the frequency of updating the filter coefficients and updating only a part of the filter coefficients. And we develop a mean square analysis to ...
