Direction-of-Arrival Estimation Through Exact Continuous ℓ2,0-Norm Relaxation

On-grid based direction-of-arrival (DOA) estimation methods rely on the resolution of a difficult group-sparse optimization problem that involves the <inline-formula><tex-math notation="LaTeX">\ell _{2,0}</tex-math></inline-formula> pseudo-norm. In this work, we sho...
