Satellite Uplink Transmission with Terrestrial Network Interference

The impact of the terrestrial network interference to a satellite uplink transmission is studied in this paper. In a system, where an LTE terrestrial network is extended by a satellite communication, the terrestrial interference can become a problem. The interference levels are studied via infield measurements and link budget calculations and the interference tolerance of the satellite receiver are studied via computer simulations. The results show that in spite of the long satellite communication link, strictly power limited system and terrestrial interference the satellite link can operate on the same frequency band as the terrestrial network.
