Abstract

In this paper, the signal reception environment of the satellite communications was analyzed on urban, suburban and rural environment. The correct analysis of received environment is very important in the satellite communications because the presence of various attenuation factors. Analyze attenuation factor through the simulation and that apply to each receiving environment. The urban and suburban various received sensitivity is determined according to building height and density. Moreover, attenuation occurs in rural areas due to the mountainous and vegetation. In this paper, we analysis of variety receiving environment according to movement of the ground station and the satellites can be utilized to provide stable multimedia services.

본 논문에서는 위성과 모바일기기 간의 전파수신감도를 수신 지역의 환경에 따라 도심지, 교외지역 그리고 시골환경으로 나누어 분석한다. 위성통신에서 수신환경에 따라 다양한 감쇠요인이 존재하기 때문에 이에 대한 정확한 분석은 매우 중요하다. 시뮬레이션을 통해 분석한 감쇠요인들을 각 수신 환경에 적용한다. 도심지는 건물의 높이와 밀집도를 높게 설정해 다양한 수신감도가 결정되고, 교외지역에서는 건물의 높이와 밀집도를 낮게 설정해 수신감도가 결정된다. 또한 시골에서는 산악지형과 식물에 의한 감쇠가 일어난다. 본 논문을 통해 지상국의 이동에 따른 다양한 수신 환경을 분석하고, 이를 통해 위성을 활용한 안정적인 멀티미디어 서비스를 제공할 수 있다.
