우리는 케이블 TV 네트워크를 통한 지상파 디지털 비디오 방송(DVB-T) 전송 품질을 연구합니다. 일반적으로 지상파 디지털 TV 신호를 케이블 TV에 분배할 경우 헤드엔드에서 DVB-T(OFDM)에서 DVB-C(단일 캐리어)로 변환이 필요합니다. 이러한 비용이 많이 드는 변환을 피하고 기존 케이블 채널에서 DVB-T 신호를 직접 전송하려면 많은 요구 사항을 충족해야 합니다. 위상 잡음은 OFDM 기반 시스템의 주요 한계를 나타내는 것으로 알려져 있습니다. 이 기여에서 우리는 CATV 채널에 대한 동적 모델을 사용하여 위상 잡음 효과에 대한 OFDM 시스템의 민감도를 보여줍니다. 그런 다음 CATV 네트워크의 변환기가 여전히 DVB-T 시스템의 기능을 허용해야 한다는 사양을 제공함으로써 결론을 내립니다.

Abstract: We study the quality of the terrestrial digital video broadcasting (DVB-T) transmission over the cable TV network. Generally, when terrestrial digital TV signals are distributed in the cable TV, a conversion is needed in the head-end, from DVB-T (OFDM) to DVB-C (single carrier). In order to avoid this costly conversion and to transmit DVB-T signal directly in the existent cable channel, many requirements have to be satisfied. It is known that phase noise represents the main limitation for OFDM based systems. In this contribution we demonstrate the sensitivity of the OFDM system for the phase noise effects by using a dynamic model for CATV channel. Then, we conclude by giving the specifications that a converter in the CATV network should have to still allow the functionality of the DVB-T system.
