Abstract
In this paper, uplink interference, which can occur when frequencies are reused, and new measures are mainly discussed. First, many different types of scenarios on uplink interference in Mobile Satellite Service in both normal and reverse mode are designed. Then the simulator which analyzes uplink interference of a user link, among interferences that can occur when reuse frequencies to make efficient use of the limited frequency resources in multi-beam satellite environments, is designed. The simulator provides the amount of interference in MSS and the way to reuse the frequency efficiently. The results of interference analysis are shown in I/N. With the given data, resolutions are proposed to minimize the interference by modifying satellite cells, diameter of the terrestrial cells, reuse of frequency and protective area.
