Abstract
In this paper, a new RT method for the calculation of radio coverage in urban environment using a virtual source tree, which is based on the numerical simulation of geometrical optics (GO) and the uniform theory of diffraction (UTD) and can solve some of the problems that other RT methods have, is presented. It is developed for two-dimensional (2-D) environments and can be applied to any complex propagation environment. It is fundamentally a point-to-point tracing method, so reception tests are not required and it guarantees high accuracy. To validate our RT method, signal path loss was calculated, and it was also compared with the published measurements. The results of the proposed method in this paper show good agreement with the measurements.
