Abstract

In this paper, we propose an equalization digital on-channel repeater (EDOCR) with a feedback interference canceller (FIC) for single frequency network of the ATSC terrestrial DTV system. The proposed EDOCR with FIC does not have only high output power by cancelling feedback signals caused by insufficient antenna isolation through the FIC, but also shows better quality of output signals than the conventional on-channel repeaters (OCRs) by removing multipath signals existing between the main transmitter and the OCR, and residual feedback signals through an equalizer. In addition, computer simulations are provided to figure out the superior performance of the proposed EDOCR with FIC.

본 논문에서는 ATSC 지상파 DTV 시스템의 단일 주파수 망 구성을 위한 궤환간섭 제거기(Feedback Interference Canceller: FIC)를 가지는 등화형 디지털 동일채널 중계기(Equalization Digital On-Channel Repeater: EDOCR)를 제안한다. 제안된 FIC를 가지는 EDOCR은 송/수신 안테나의 충분치 못한 분리도로 인해 야기된 궤환신호를 FIC를 통해 제거함으로써 송신출력을 높일 뿐만 아니라, 등화기를 통하여 송신기와 중계기 간 다중경로 신호 및 잔존하는 궤환신호를 제거하여 기존의 동일채널 중계기 보다 우수한 출력신호 품질을 보장한다. 또한, 본 논문에서는 전산실험을 통해 FIC를 가지는 EDOCR의 성능의 우수성을 검증한다.
