Abstract

Problems such as a limited frequency resource and interference between adjacent bands have been continuously raised because of rapidly developing wireless technology and communication service. In order to solve that problem, government has been developed and operating the Spectrum Management Intelligent System(SMIS). This paper compares the results simulated by SMIS with the ATDI and the Matlab coded provided by ITU-R for verification of SMIS operating for the public interests. The Recommendation ITU-R P.526, P.1546, and P.1812 among the propagation model loaded in SMIS were chosen because of the relation to the broadcasting service. The comparison and analysis result shows that the outputs derived by SMIS has the small error of less than 1 dB. This research could be utilized for the policy establishment and R&D for the frequency allocation and the interference between adjacent bands.

무선기술 및 통신 서비스의 급속한 발전에 따라 주파수 자원의 부족과 인접 대역 전파 간섭 등의 문제가 지속적으로 제기되고 있다. 해결방안으로 정부에서는 주파수자원분석시스템(Spectrum Management Intelligent System, SMIS)을 운영 중이다. 본 논문은 주파수자원분석시스템의 신뢰성을 검증하기 위하여, SMIS 시뮬레이션 값을 상용툴 ATDI 결과값 및 ITU-R Matlab 코드 결과값과 비교하였다. 전파 모델 중 방송망과 연관이 있는 권고서 ITU-R P.526, P.1546, P.1812를 선정하였다. 분석 결과, SMIS의 추출값은 전체적으로 1dB이내의 작은 오차를 갖는다. 본 연구는 향후 주파수 분배와 인접 대역간 간섭분석 정책 수립과 연구 개발 등에 활용될 수 있을 것으로 예상한다.
