Sparse Adaptive Channel Estimation Based on lp-Norm-Penalized Affine Projection Algorithm
We propose an lp-norm-penalized affine projection algorithm (LP-APA) for broadband multipath adaptive channel estimations. The proposed LP-APA is realized by incorporating an lp-norm into the cost function of the conventional affine projection algorithm (APA) to exploit the sparsity property of the...
