Abstract EN
The problem of the direction of arrival (DOA) estimation for the noncircular (NC) signals, which have been widely used in communications, is investigated.
A reduced-dimension NC-Capon algorithm is proposed hereby for the DOA estimation of noncircular signals.
The proposed algorithm, which only requires one-dimensional search, can avoid the high computational cost within the two-dimensional NC-Capon algorithm.
The angle estimation performance of the proposed algorithm is much better than that of the conventional Capon algorithm and very close to that of the two-dimensional NC-Capon algorithm, which has a much higher complexity than the proposed algorithm.
Furthermore, the proposed algorithm can be applied to arbitrary arrays and works well without estimating the noncircular phases.
The simulation results verify the effectiveness and improvement of the proposed algorithm.
