Proportionate Affine Projection Algorithms for Block-sparse System Identification
Jianming Liu, Steven L. Grant
A new family of block-sparse proportionate affine projection algorithms (BS-PAPA) is proposed to improve the performance for block-sparse systems. This is motivated by the recent b…
Block Sparse Memory Improved Proportionate Affine Projection Sign Algorithm
Jianming Liu, Steven L. Grant
A block sparse memory improved proportionate affine projection sign algorithm (BS-MIP-APSA) is proposed for block sparse system identification under impulsive noise. The new BS-MIP…
Proportionate Adaptive Filtering for Block Sparse System Identification
Jianming Liu, Steven L. Grant
In this paper, a new family of proportionate normalized least mean square (PNLMS) adaptive algorithms that improve the performance of identifying block-sparse systems is proposed.…
An Improved Variable Step-size Zero-point Attracting Projection Algorithm
Jianming Liu, Steven L. Grant
This paper proposes an improved variable step-size (VSS) scheme for zero-point attracting projection (ZAP) algorithm. The proposed VSS is proportional to the sparseness difference…
A New Variable Step-size Zero-point Attracting Projection Algorithm
