ABSTRACT
In this paper, we propose Propagation Path-loss models for terrestrial ATSC (Advanced Television Systems Committee) DTV (Digital Television) using the results of ATSC DTV field-test measurements in Seoul, Korea in 2001. Numerical formulae of proposed Path-loss models are derived from the measured values of received field strength. Newly proposed Path-loss models have closer correctly agreement with the field-measured results than these of conventional Path-loss models ( e.g., Free space model, Friss model, Hata model, 2-Ray model, ITU-R 526-3 model and Lee model) in the LOS(Line of Sight) and Non-LOS areas. Path-loss models presented in this paper can be readily utilized usefully for efficient ATSC DTV system implementation requiring accurate link-budget calculation.
