Figure 8From: Subspace weighted ℓ2,1 minimization for sparse signal recoveryRobustness of SW ℓ 2,1 -SVD to the assumed number of sources. (a) ANS = 0; (b) ANS = 1; (c) ANS = 6; (d) ANS = 8. The data window size is 32. Asterisk-solid curve: ℓ1-SVD; square-dash curve: SW ℓ2,1-SVD; solid curve: MUSIC; triangle-up: true spacing.Back to article page
