Analysis of Special Interference Methodologies in Satellite Networks

In this paper the effects of interference of non-geostationary orbit (GSO) satellite with GSO satellite services is calculated. As these effects are calculated in frequencies up to 30 GHz, the interference with the assumption of given GSO satellite parameters (such as BER C/N) is determined considering rain fade. For calculation of C/I in this paper, we first introduce various methodologies which are used to calculate maximum allowable level of interference. Then using these methodologies, EPFD (the equivalent power flow density) is calculated. Finally, a computer program is developed using one of these methodologies and comparison is made with an ITU (International Telecommunication Union) model which shows good agreement.
