Figure 2From: Subspace weighted ℓ2,1 minimization for sparse signal recoveryDOA tracking performance for two uncorrelated mobile sources. (a) Root-MUSIC; (b) ℓ1-SVD; (c) SW ℓ2,1-SVD. SNR is 12 dB, the number of snapshots T = 3. The solid lines and "·-" denote the trajectories of the true DOAs and the estimates, respectively.Back to article page
