A New Smoothed L0 Regularization Approach for Sparse Signal Recovery

Figure 2

Signal recovery in noiseless case. RSR and NMSE of recovery signal are displayed at intervals of 5 with sparsity from 1 to 61. The comparison algorithms are BPDN, SL0, L2-SL0, Lp-RLS, and RRSL0. The experimental results were obtained by 100 independent repeated experiments.

(a) RSR of recovery signal
(b) NMSE of recovery signal
