| Abstract(in English) | In this paper, we evaluate the propagating-path identification using FDTD (Finite-Difference Time-Domain) method and compressive sensing. In this method, Yee cells are regarded as an array antenna, and a DOA (direction-of-arrival) estimation based on array signal processing technique is used for propagation path identification. This study deals with a compressive sensing technique, which realizes a high-resolution DOA estimation without prior information of the number of incoming signals. Since the accuracy of DOA estimation significantly impacts the accuracy of the path identification, the effect of the aperture-width and sampling resolution of the observing field on the estimation results was evaluated. The analysis results indicated that the sampling interval less than quarter wavelength and the aperture-width about 1.2 wavelengths clarify the propagation pathbetter than all other parameters dealt with in this study. |
