| Abstract(in English) | The ray tracing method is expected to be more widely used in indoor and outdoor micro cells where analysis is more active in recent years. It will also be used for real-time ray tracing, applications to moving objects, and high frequency (802 .11ad [3] and 5G [4]). Therefore, the calculation reduction is required to expand usage scenarios. In this paper, we studied the method to calculate the average received power quickly for each mesh that divides the analysis area into a fixed size. This method is the several times of ray tracing calculations with less number of diffractions by using the simplified structure. Then, the interpolation post-processing to the ray tracing results were performed. As a result, it was found that the accuracy of two diffractions and post-processed result was equivalent to that of three diffractions. Finally, about 5 times acceleration was achieved. |
