Abstract
KBS and ETRI have co-developed an advanced DOCR(Digital On Channel Repeater) which has an equalization and pre-distortion function and can be operated properly under lower isolation of reception and transmission antennas. Field tests of the DOCR were performed twice in Suwon area in 2004 and 2005. This paper summarizes the characteristics of the DOCR system and field test results in Suwon. The changes in DOCR coverage according to the different generations of ATSC DTV receivers were also analyzed. Basic concept to apply the DOCR system in DTV broadcasting networks in Korea is suggested through test results.
