Abstract

In this paper, we presented interference scenarios and an evaluation methodology for the co-frequency radio interference between a multi-beam mobile satellite communication system and a mobile communication system in 2.1 GHz band. Radio interferences between these systems are calculated using a minimum coupling loss method and an assesment for minimum separation distances was conducted for coexistence of a mobile satellite system and a mobile system in the same geographical area.

본 논문에서는 2.1 GHz 대역 다중빔 이동위성통신 시스템과 이동통신 시스템간 간섭 시나리오를 분석하고, 두 시스템간 주파수 공유를 위한 간섭 평가 방법을 제시하였다. 최소결합손실 방법을 이용하여 이동통신 시스템으로부터 이동위성통신 시스템으로의 간섭 및 이동위성통신 시스템으로부터 이동통신 시스템으로의 간섭 분석을 수행하였으며, 분석 결과로부터 두 시스템간의 동일 주파수 공유를 위한 이격 거리를 도출하였다.
