본 논문에서는 ATSC 디지털 TV (DTV) (Equalization Digital On-Channel Repeater)를 위한 복조, 등화, 그리고 재변조로 구성된 디지털 신호 처리 (Digital Signal Processing: DSP) 기술들을 제안한다. EDOCR에서의 신호처리 과정에 의해 발생되는 시스템 지연은 기존 수신기의 수신 성능 저하를 야기할 수 있기 때문에 가능한 그 지연을 최소 화 하여야 한다. 본 논문에서 제안한 DSP 기술들은 EDOCR의 성능 저하를 최소화 하면서 시간 지연을 줄일 수 있도록 하였다 . 또한, 본 논문에서는 전산 실험을 통해 하드웨어 구현에 적합한 필터의 탭 수를 다양하게 제시한다.
