디지털 TV 적용을 위한 부산지역 전파환경에 관한 연구

Abstract

Recently, the trends of broadcasting technology are transformed analog broadcasting to digital broadcasting.

This is the why digital broadcasting technology offers multimedia services such as home shopping or home banking, internet searching, telecommunication, VOD etc.

Therefore, it is necessary to analyze radio propagation environment of digital broadcasting service area.

However, it is very difficult to apply the conventional propagation models for Busan urban area where are a lot of mountain and hill.

Among the conventional propagation models, ETRI propagation model is very optimal for analyzing the radio propagation environment in Busan area.

This thesis is analyzed geographical propagation characteristics with ETRI propagation model and is measured the field strength for digital broadcasting at UHF band.

Finally, this thesis is compares simulation values based on ETRI propagation model with measured values, and analyzes radio propagation environment.

This thesis suggests suitable radio propagation model in Busan urban area.
