Abstract

This paper represents measurement prodcedure and analysis of terrestrial DTV field test results over Taejeon city area. Thirty three points were selected as measuring points. Signal power, noise power, Segment Error Rate, RMS delay spread and equalizer performance was measured. The video and audio quality of DTV was good over half of test sites. Equalizer, could correct signal ghost and improve S/N up to 13.7 dB. From this test, the test procedure for DTV will be estabilished.

약 2에 걸쳐서 대전지역을 대상으로 DTV 현장측정을 실시하였다. 총 33개의 측정지점을 선정하였고 각 지점에서 수신전력, 잡음전력, SER, RMS 지연확산 및 등화기의 성능을 측정하였다. 전체 측정지점 중의 약 50%가 영상과 음성의 질이 만족할 만한 수준이었고, 등화기는 고스트신호에 대하여 보상능력이 있었으며 13.7dB의 S/N개선을 얻었다. 이 결과로부터 DTV를 위한 측정결과를 확립할 수 있을 것이다.
