초록

본 연구에서는 우리나라 DTV 방송의 대역외발사강도 기술기준 및 기존 측정방식의 문제점들을 분석하였으며, 지상파 DTV 방송의 대역외발사강도를 효과적으로 측정할 수 있는 방안들을 제안하였다. 고가의 전용 측정장비로만 측정가능한 기존방식에 비해 제안한 방식은 범용장비로도 대역외발사강도를 손쉽게 측정할 수 있으며, 실제 측정시스템 구현을 통하여 제안한 방식의 유효성을 입증하였다. 본 논문에서 제안된 방식은 경제적이고도 간편하므로 방송장비 이외의 무선 송신장치 특성측정에도 널리 사용될 수 있다.

In this paper, out-of-band emission regulations and measurement methods of terrestrial DTV broadcasting services are analyzed, and a novel method to evaluate the out-of-band emission characteristics of DTV transmitter is proposed. Experimental results show that proposed method can be easily used to measure the characteristics of DTV transmitter with inexpensive measuring equipments. With a few modifications, proposed method can be widely adopted to measure the RF performances of the general radio equipments efficiently.
