Intelligent transportation systems (ITSs) are currently under intense research and development for making transportation safer and more efficient. The development of such vehicular communication systems requires accurate models for the propagation channel. A key characteristic of these channels is their temporal variability and inherent time-changing statistics, which have a major impact on electromagnetic...
The combination on an algorithm based on Geometrical Optics (GO) and diffraction calculation on the basis of the Uniform Theory of Diffraction (UTD) is presented in this paper. The aim is to improve the basic Ray Launching code, based on GO, which takes into account reflected and refracted rays. With the UTD extension, further propagation of diffracted rays is also considered. The comparison with...
