Abstract

In this paper, we consider the frequency sharing feasibility of Fixed Satellite Service (FSS) with Microwave Landing System (MLS) allocated in the C-band. On the basis of characteristics of MLS and FSS suggested by ITU and safety standards of MLS by ICAO, three interference scenarios are built and numerical simulations are carried out for investigating the frequency sharing between the two systems. From the simulation results, we calculate the separation distance between MLS and FSS ground antennas, required for frequency sharing by employing standard protection limits regulating the interference to noise ratio (I/N) of the receiver.

본 논문에서는 C-대역에서 1차 업무로 할당되어 있는 마이크로파착륙장치 (MLS)와 고정위성업무 (FSS) 간 주파수 공유 가능성을 검토한다. ITU에서 국제표준으로 제시하고 있는 MLS와 FSS의 특성을 적용하고 국제민간항공기구 (ICAO)의 MLS 안전기준을 고려하여 간섭에 대한 3가지 시나리오를 구성하고 시뮬레이션을 통해 주파수 공유가능성을 분석한다. 시뮬레이션 결과로부터 공유를 위한 수신기 허용간섭기준 및 I/N (간섭대 잡음전력비) 보호기준을 사용하여 MLS 지상국과 고정위성업무 지구국의 이격거리를 산출한다.
