Figure 3From: Subspace weighted ℓ2,1 minimization for sparse signal recoverySpatial spectrum for coherent sources. (a) MUSIC; (b) ℓ1-SVD; (c) SW ℓ2,1-SVD. Three sources at 12°, 43°, and 67°, and each power is 10 dB. Green circles denote the DOAs and power of sources in each plot. 100 Monte-Carlo trials are shown.Back to article page
