위성중계기 입력방송파군의 최적전력할당 및 주파수 배치에 따른 성능평가 = Preformance evaluation for optimal power assignment and frequency plan of carrier groups

다국어 초록 (Multilingual Abstract)

As a method for effective utilization of the limited power and frequency resources in satellite communications, this paper develops software which can assigns the optimal power of input carrier groups inthe multi-level SCPC systems and performs evaluation to a various satellite link environment. Using the developed software, the paper presents performance according to the frequency plan of carrier groups and suggest a frequency play method for performance improvement of satellite link. A various interference and noise caused by satellite link are analyzed for reliable performance evaluation. The performance criteria for evaluation is classified into 2 categories according to the CNR of destination receiver earth station.
