Figure 1From: Subspace weighted ℓ2,1 minimization for sparse signal recoveryRMSE of angle estimation. (a) Uncorrelated sources. (b) Coherent sources. The number of snapshots is T = 200. Each point is average of 500 Monte-Carlo trials. Asterisk-solid curve: ℓ1-SVD; Square-dash curve: SW ℓ2,1-SVD; Circle-solid curve: Root-MUSIC; Dash curve: CRLB.Back to article page
