Abstract： According to the design requirements of satellite X-band communication system link, studying detailly various losses, interferences in the transmission process, system indexes and characteristics,，a variety of link calculation methods for uplink/downlink, single/dual channels of satellite communication system are proposed, and the feasibility of the calculation model is verified by practical examples. The calculation method model can be used for parameter selection of satellite communication system, prediction of signal quality and link capability, and it has guiding significance for the design of satellite communication system.
Key words : satellite communication,；link calculation；uplink/downlink and single/dual channel,；carrier noise ratio
