Abstract

This paper considers technological requirements to broadcast digital television signals using distributed frequency network (DFN) in the advanced television systems committee (ATSC) transmission system and proposes distributed translator (DTxR) to meet such requirements. In the DFN, DTxR uses different frequency from main transmitter, but same among DTxRs. In addition, this paper introduces digital signal processing (DSP) techniques, which consist of demodulation, equalization, transmitter identification (TxID) generation and insertion, and modulation, to implement DTxR.

본 논문에서는 ATSC (Advanced Television Systems Committee) 지상파 디지털 TV 방송 방식에서의 분산 주파수 망(distributed frequency network: DFN)의 특징 및 기술적인 요구 사항에 관해 고찰하고, 그 요구사항을 만족하기 위한 분산중계기(Distributed Translator: DTxR)를 제안한다. DFN은 송신기와 중계기는 서로 다른 주파수를 사용하지만 동일한 송신기 신호를 중계하는 모든 중계기들 간에는 동일한 주파수를 사용하는 방송망이다. 또한, 본 논문에서는 DTxR 구현을 위한 복조, 등화, TxID (Transmitter Identification) 생성 및 삽입, 변조, 그리고 중계기간 주파수 일치 등과 같은 신호처리 기술을 소개한다.
