| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents a novel Direction-Of-Arrival (DOA) estimation method based on the fact that the correlation between received signals at different antenna elements can be written as a function of DOAs. MUSIC (Multiple Signal Classification) and ESPRIT (Estimation of Signal Parameters via Rotational Invariance Techniques) methods are the representative DOA estimation algorithms due to their high estimation accuracy. However, those algorithms employ eigendecomposition which requires very large computational cost. Moreover, in the case of correlated incident waves, they require space averaging technique which reduces the practical number of antenna elements. In this paper, we propose a simple DOA estimation algorithm based on the fact that the correlation between the received signals at different antenna elements can be written as a function of DOAs. Although the proposed method needs more array elements in comparison with MUSIC method to estimate the same number of DOAs, the computational cost of the proposed method is much smaller than that by MUSIC method. Moreover, the present method does not require the space averaging technique even though the case of correlated incident waves. The estimation accuracy and the computational cost are evaluated through computer simulation in comparison of those by MUSIC and Beamformer methods. |
