Abstract
최근 우리나라는 증가하는 모바일 트래픽 수요를 감당하기 위해 최대한 많은 주파수대역을 확보하기 위해 노력하고 있다. 우리나라가 확보하기 위해 노력하고 있는 주파수 대역 중, 2.1GHz 대역은 이동시스템과 위성시스템의공동사용이 허가된 대역이다. 그러므로 이동시스템을 사용하는 국가의 인접국이 동대역에 위성시스템을 운용하는경우 전파 간섭이 발생할 수 있으므로 적절한 간섭평가방법이 필요하다. 현재 대부분의 간섭은 최소결합손실방법으로 평가되고 있기 때문에 실제의 간섭수준을 잘 표현하지 못하는 경우가 많다. 이 논문에서 우리는, 몬테-카를로방법을 이용해 두 시스템의 공존가능성을 평가하기 위한 모의실험 방법을 제안한다. 또한, 모의실험을 통해 간섭평가 결과를 제공했다.
