	| Abstract | 
	This paper proposes a novel affine projection algorithm (APA) based on L0-norm constraint for improving the convergence rate in a sparse system. The proposed APA guarantees a fast convergence rate owing to the effect of L0-norm constraint. Experimental results confirm that implementing the proposed APA enhances the performance of adaptive filter for sparse system identification.  |
