Abstract :
This paper proposes a novel equalization digital on-channel repeater (EDOCR) with a feedback interference canceller (FIC) for a single frequency network (SFN) of the advanced television systems committee (ATSC) terrestrial digital television (DTV) system. The proposed EDOCR with an FIC not only has high output power by the cancellation of feedback signals caused by insufficient antenna isolation through the FIC, but also shows better quality of output signals than conventional digital on-channel repeaters (DOCRs) by removing multipath signals existing between the main transmitter and DOCR, as well as residual feedback signals through an equalizer. Computer simulation results are provided to demonstrate the superior performance of the proposed EDOCR with an FIC.
