Abstract

This paper proposed an improvement scheme for effective usage of radio-frequency management system(RFMS), which has been operated to facilitate national spectrum management and monitoring in Korea. Based on the wave propagation models, interference analysis algorithms, and sharing criteria recommended by ITU-R, we derived criteria for the automated selection of the channel interference analysis algorithms and sharing conditions adequate to the environment to be analysed. Then using the obtained criteria, computer and program has been made and shown to select the most appropriate propagation models, interference analysis algorithms, and sharing criteria from the ones provided in RFMS, with the illustrative example.

본 연구에서는 전파관리시스템(RFMS)의 효율적 운용을 위하여 전파전파 분석 기능 개선 방안을 도출하였다. 즉, ITU-R에서 권고하는 파라미터별 전파전파 알고리즘, 간섭분석 알고리즘 및 공유기준들에 대한 체계적인 분석을 수행한 후, 사용자가 원하는 환경 및 조건에 적합한 전파간섭 분석 알고리즘과 보호기준을 자동으로 선택해 낼 수 있는 모델 선정 기준안을 도출하였다. 이 결과를 이용하여 RFMS에서 최적의 전파 간섭 분석 알고리즘을 자동 선택하여 효율적으로 분석을 수행하도록 해주는 프로그램 및 그 활용 예를 제시하였다.
