In this paper, we evaluate the accuracy of the propagating-path identification using Finite-Difference Time-Domain (FDTD) method and compressive sensing in multipath environment. In this proposed method, two kinds of electromagnetic fields are calculated by switching transmission (Tx) and reception (Rx), and the components contributing to the propagation between the Tx and Rx are extracted from the electromagnetic field, in which the multipath waves exist. Eath of the electromagnetic field of Yee cell is regarded as an antenna, and arrival wave is separated by compressive sensing technique, which is a kind of array signal processing. From the reciprocal theorem, when the directions of the arrival waves with forward and backward transmissions are opposite to each other, it is determined that these waves contribute propagation between Tx and Rx. In our previous study, we evaluated the improvement of the estimation accuracy in a simple Line-of-Sight (LOS) model. However, we did not consider the path identification in a complicated model close to the real environment. Therefore, the estimation accuracy of the proposed method under the multiple wave environments is evaluated by using several quasi Non-Line-of-Sight (NLOS) models. The analysis results clarified that the proposed method can visualize paths even in the complicated environments. |
