Sažetak
The paper presents an example of satellite propagation modeling, applying the radio channel transfer function analysis as described and experimentally verified in scientific literature. The simulation of a satellite radio channel is executed by employing "ray-tracing" and the Uniform Geometrical Theory of Diffraction based method for an assumed urban and suburban environment and different polarizations. Derived results regarding the channel transfer function are analyzed via a simulation of the Wide-Band Propagation Measurement System and the Fourier Transform procedures. It has been concluded that, contrary to ground cell radio system situations where two-ray models usually suffice, for wide-band satellite radio systems a more detailed calculation should be considered. Moreover, it is shown that the conclusions derived for the path-loss and the delay-spread depend not only on the specific propagation scenario, but on the building permittivity as well.
