Abstract

Since radio interference can degrade the performance of systems or limit the system operation, an accurate assessment of radio interference with the existing systems should be conducted prior to the operation of a new system. In this paper, we present an evaluation methodology for the radio interference between radio-navigation satellite service (RNSS) systems and mobile communication service (MS) system. Radio interferences from RNSS systems into MS system using minimum coupling loss (MCL) method are simulated and vice-versa, and the frequency sharing condition between two systems are derived in a same geographical area.

무선통신 시스템 간의 주파수 간섭은 시스템의 성능을 감소시키거나 운용을 제한할 수 있으므로 신규 시스템의 도입 이전에 기존 시스템들과의 주파수 양립성 평가가 반드시 수행되어야 한다. 본 논문에서는 1.6 GHz 대역 무선항행위성업무 시스템의 인접대역에서 신규 이동통신업무 시스템을 운용하기 위한 양립성 평가 알고리즘을 제시하였으며, 동일 지역 내에서 운용되는 이동통신업무시스템과 무선항행위성업무 시스템 상호 간의 최소결합손실 (Minimum Coupling Loss; MCL) 분석 결과로부터 두 시스템 간의 주파수 공유를 위한 조건을 도출하였다.
