Abstract
ABSTRACTIn this paper, we incorporate an ℓp-norm sparsity constraint into linear phase constrained affine projection-sign algorithm (LPCAP-SA). The proposed algorithm combines the effect of linear phase constrained affine projection sign algorithm and ℓp-norm sparsity constraint .The proposed algorithm has better performance for linear phase sparse system identification in the presence of vigorous impulsive interference. The proposed ℓp-norm LPCAP-SA is based on the ℓ1-norm minimisation criterion on posterior error and ℓp-Norm on weight coefficients and a linear phase constraint. Simulations in Matlab software show that the proposed ℓp-norm LPCAP-SA has robustness against impulsive interferences and sparse environment for linear phase system.
