Proportionate affine projection algorithms for block-sparse system identification

ICASSP 2016accepted

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 block-sparse proportionate normalized least mean square (BS-PNLMS) algorithm. It is demonstrated that the affine projecti…

An improved variable step-size zero-point attracting projection algorithm

Jianming Liu, Steven L. Grant

ICASSP 2015accepted

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 between filter coefficients and the true impulse response. Meanwhile, it works for both sparse and non-sparse system ide…
