Figure 1From: On recovery of block-sparse signals via mixed l 2 /l q (0 < q ≤ 1) norm minimization A typical simulation result with different estimated block-sparsity. The randomly generated signals have length N = 256, m = 64 uneven size blocks, and k = 9 active blocks with total sparsity k 0 = 22. We observed m = 64 measurements and the average RMSE over 100 independent random trails in the logarithmic scale is shown.Back to article page
