Abstract

본 연구에서는 중소규모 지상파 DTV 방송의 난시청지역 해소를 위하여 우리나라 및 외국의 기술현황 및 관련 기술기준들을 고찰하였다. 이를 이용하여 출력 10mW/MHz 이하인 특정 소출력 디지털 텔레비전(DTV) 방송중계용 무선기기의 송신 요구기준을 제안하였으며, 실험을 통하여 제안한 방식의 유효성을 입증하였다. 본 논문에서 제안한 방식은 기존 방식에 비해 경제적이고도 소형으로 중계기를 구현할 수 있어 수 km 미만의 중소규모 난시청 지역이 많이 발생하는 우리나라 DTV 수신환경 개선에 널리 사용될 수 있다. In this paper, worldwide standards and regulations on broadcasting services are reviewed to improve the fringe area of terrestrial DTV broadcasting services. Using these results, in-band/out-of-band emission requirements of low power DTV repeater with 10mW/MHz radiating power are proposed, and experimentally evaluated and verified. Using the proposed regulations, compact and cost-effective DTV repeater can be easily implemented to broaden DTV broadcasting coverage and to improve small/medium size DTV fringe areas.
