Deterministic Wide-Band Modeling of Satellite Propagation Channel with Buildings Blockage

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.
