The Compressed Nested Array for Underdetermined DOA Estimation by Fourth-order Difference Coarrays

In this paper, a new sparse array structure, which further improves the degrees of freedom (DOFs) and enhanced the DOA estimation performance, for the fourth-order cumulant based direction of arrival (DOA) estimation is proposed. The new-formed array is hole-free and can achieve a large consecutive…
