Smooth Approximation l (0)-Norm Constrained Affine Projection Algorithm and Its Applications in Sparse Channel Estimation

We propose a smooth approximation l (0)-norm constrained affine projection algorithm (SL0-APA) to improve the convergence speed and the steady-state error of affine projection algorithm (APA) for sparse channel estimation. The proposed algorithm ensures improved performance in terms of the convergen...
