무선 마이크에 대한 DTV 서비스 간섭 영향 분석 = The Interference Effect of DTV Service on Radio Microphone

다국어 초록 (Multilingual Abstract)

This paper analyzes potential interference effect of DTV service on Radio Microphone in adjacent channel. For analysis, we assume that DTV operates on CH 51(692 MHz ∼ 698 MHz) and radio microphone operates on CH 52 (698 MHz ∼ 704 MHz) according to the Korea Communications Commission policy. Minimum Coupling Loss(MCL) method is used to determine the required protection distance and Monte Carlo method is used to determine guard band to meet interference probability of 0 % below. In conclusions, protection distance of 1.71 km and guard band of 2.4 MHz are required for indoor and protection distance of 18.86 km and guard band of 5.7 MHz are required for outdoor.
