| Abstract: | In the direction of arrival (DOA) estimation problem, the relationship between the second-order and the fourth-order subspaces is found and proved in the paper. The fourth-order cumnlant based minimum norm(Min-Norm) method is proposed. The formnla of the cumnlant based root Min-Norm under uniform linear array model is presented and the numerical examples in given. |
