A DOA estimation algorithm based on the low computational complexity log-sum sparse recovery

•Research highlight 1To further reduce the computational complexity of the KA-SURE-IR and SURE-IR, this paper proposes a low computational complexity log-sum sparse recovery algorithm to achieves DOA estimation. The realization of the low complexity is realized by designing a new descent direction,...
