Accuracy analysis of propagating-path identification using FDTD method and compressive sensing

摘要

In this paper, we propose a propagating path identification method using Finite-Difference Time-Domain (FDTD) method and compressive sensing. In this study, Yee cells are regarded as array antenna, and the compressive sensing is introduced to identify direction-of-arrival of the radio waves. In this method, the signal is alternately transmitted between two antennas, and the DOAs are estimated for each case. By using estimated DOA information for these two cases, the propagating paths can be identified. Also, we evaluated the impact of the number of the array antenna elements and element separation on the accuracy in estimating the propagating paths.
