지상파 DTV 동일채널 중계기 필드 테스트 결과 분석
Abstract
This paper represents analysis of field test results of terrestrial DTV on channel repeaters over Taejon city area. Two kind of on channel repeaters were tested. Non-regenerative repeater performs filtering, amplifying and re-transmit received main DTV signal. Regenerative repeater performs demodulation, modulation and amplifying and re-transmit received main DTV signal. The non-regenerative repeater threshold D/U ratio is about 10dB better than regenerative repeater's one.
