An Off-Grid DOA Estimation Method Using Proximal Splitting and Successive Nonconvex Sparsity Approximation
Direction-of-arrival (DOA) estimation is a fundamental problem in many signal processing. Recently, a variety of sparsity-aware methods have been proposed for DOA estimation. The discrimination of grid in these methods often suffers from grid mismatch problem, which degrades the performance of DOA e...
