| Abstract(in English) | Direction of arrival (DOA) estimation of radio waves is applicable to localization of wireless terminals and radar systems. In addition to MUSIC and ESPRIT, which are well-known traditional algorithms, compressed sensing has been applied to DOA estimation. Compressed sensing has a higher accuracy compared with MUSIC in general but requires larger computational load. If such a large computational load is acceptable, we can consider to apply deep learning to DOA estimation. In this paper, we propose an estimation method using deep learning, especially with an additional network designed for closely located sources, and examine its basic characteristics in the case where two narrow-band signals impinge on a linear array. The simulation results show that high estimation accuracy is obtained and that the performance depends on the learning data sets. |
