This paper presents a novel off-grid direction of arrival (DOA) estimation method to achieve the superior performance in compressed sensing (CS). in which DOA estimation problem is cast as a sparse reconstruction. By minimizing the mixed k-l norm. the proposed method can reconstruct the sparse source and estimate grid error caused by mismatch. https://www.jmannino.com/special-deal-A-Magazine-Curated-By-Sacai-quick-pick/
