Description

technical field

[0001] The invention relates to the technical field of satellite communication, in particular to a sliding mode predictive congestion control system suitable for satellite space information transmission network. Background technique

[0002] After the completion of the Beidou satellite network in 2020, it has started a large-scale commercialization of industrial integration and has achieved good benefits in aerospace, agriculture, manufacturing, and breeding industries. More and more industries will use Beidou satellites Realize information transmission. However, the communication performance of Beidou satellites has always been the bottleneck problem restricting its own development. Nowadays, when the number of Beidou receiving equipment on the ground continues to expand, because the satellite link bandwidth cannot be easily increased, when the satellite system cannot bear the large amount of data sent from the ground, The communication link of the satellit...
