초록

This paper represents analysis of field test results of terrestrial DTV on channel repeaters over Taejon city area. Two kind of on channel repeaters were tested. Non-regenerative repeater performs filtering, amplifying and re-transmit received main DTV signal. Regenerative repeater performs demodulation, modulation and amplifying and re-transmit received main DTV signal. The non-regenerative repeater threshold D/U ratio is about 10dB better than regenerative repeater's one.
