| Abstract(in English) | In a variety of communication systems, multipath propagation due to various reflections is often encountered. In this paper, the directions-of-arrival(DOA) estimation of the cyclostationary coherent signals is investigated. A new approach is proposed for estimating the DOA of the coherent narrow-band signals impinging on a uniform linear array(ULA) by utilizing the spatial smoothing(SS) technique. In order to improve the robustness of the DOA estimation by exploiting the cyclic statistical information sufficiently and handling the coherence effectively, we present a cyclic algorithm with multiple lag parameters and the optimal subarray size. The performance of the presented method is verified and compared with the conventional methods through numerical examples. |
