From: On recovery of block-sparse signals via mixed l 2 /l q (0 < q ≤ 1) norm minimization
Recovery results with M = 144 . (a) Original signal; (b) results with l q (q = 0.7) minimization (RMSE = 0.3589); (c) results with l q (q = 0.5) minimization (RMSE = 0.3857); (d) results with l q (q = 0.1) minimization (RMSE = 0.4124); (e) results with l 2/l 1 minimization (RMSE = 0.1688); (f) results with l 2/l q (q = 0.7) minimization (RMSE = 0.1164); (g) results with l 2/l q (q = 0.5) minimization (RMSE = 4.21 × 10-7); (h) results with l 2/l q (q = 0.1) minimization (RMSE = 8.23 × 10-8).
