Abstract :
We have proposed to simulate the propagation characteristics of the satellite-to-indoor propagation channel. Our first goal has been to find a proper description of the polarization state of the received indoor wave. As far as our first investigations lead us, the polarization state of the indoor wave basically changes as we move further away from the windows, i.e. the secondary source of radiation. First we investigate how the polarization state of a complex harmonic field can be described, then results regarding our first simulations of the polarization state are presented. A modified 3D ray-launching tool has been utilized for the coverage prediction. Further work will include an exhaustive analysis of the dependence of the indoor wave on the elevation angle of the satellite, and the wideband characteristics of the channel: delay spread characteristics and Doppler spread, caused by satellite motion
