Development of Radio-wave Propagation Model for DTV Signal Characteristic Analysis in Domestic Environment

국내 환경에서의 DTV 전파특성 분석을 위한 전파전파 모델 개발

A development scheme for reliable radio-wave Propagation model of digital television (DTV) service, adequate to the domestic environment, is proposed in this paper. Throughout the analysis of several ITU-R recommendations on propagation models in DTV band, ITU-R P.1546, which is based on experimental data, has been selected as our basic model. This model has been programmed, not only to be directly used for engineering analysis, such as frequency assignment, licensing, interference analysis, and sharing frequency bands, but also to be applied for development of a propagation model adequate to the specific environment. Furthermore, the procedure of developing domestic propagation model for DTV service, combined with experimental data which is now being obtained, has been described in this paper.
