Sparse Signal Recovery for Direction-of-Arrival Estimation Based on Source Signal Subspace
After establishing the sparse representation of the source signal subspace, we propose a new method to estimate the direction of arrival (DOA) by solving an ℓ1-norm minimization for sparse signal recovery of the source powers. Second-order cone programming is applied to reformulate this optimization...
