ISM 기기에 의한 디지털 방송 서비스 간섭 영향 분석

다국어 초록 (Multilingual Abstract)

This paper analyzes the interference effect of ISM(Industrial Scientific Medical) equipment on Digital Broadcasting Service in ISM frequency band. For setting up interference power of ISM equipment, CISPR(International Special Committee on Radio Interference) 11 radiation limit standard was used. Then, MCL(Minimum Coupling Loss) which is for worst case and MC(Monte Carlo) which is for statistic analysis considering mobility of digital broadcasting receiver are used to get protection distance. Finally, according to each channel number 14, 40, 60, protection distance of 184.97m, 104.67m, 73.79m were calculated separately for the worst case. The protection distance of 29m to meet 5% of interference probability was calculated for statistic analysis regardless of channels. As a result, this protection distance was suggested to protect digital broadcasting service from ISM devices.
