| Abstract: | The link budget of the satellite communication is the process which deals with all sorts of the technical parameters for the station design.By calculating and analysis,the user can reasonably change parameters such as antenna size or change the antenna gain,the modulation,the choice of high quality LNB or BUC,and the low-loss cables to meet the quality,price,scalability,and other requirements of the system.This paper describes in detail the process of the satellite transmission link budget and the results a... |
