Abstract

The invention discloses a satellite-ground cooperative wide-area real-time communication system and a communication method thereof, and relates to the technical field of satellite-ground cooperative communication, and the communication method comprises the following steps: deploying a satellite-ground cooperative network, configuring initial link parameters and node identifiers of a satellite and a ground station, and establishing a link state table; the link state data in the link state table are fed back to the control end, and the control end calculates a link comprehensive score based on the link state data; according to the real-time optical communication channel state and the interference condition, the light beam direction is dynamically adjusted, communication channel reconstruction is carried out, and the optimal optical communication channel is selected; transmitting the encoded data stream to a receiving end through the optimal optical communication channel, and decoding the encoded data stream by the receiving end through a decoder to generate link quality data; and updating the link state table according to the link quality data. Based on the real-time optical communication channel state and the interference condition, the light beam direction is dynamically adjusted, the communication channel is reconstructed, the optimal transmission path of the channel is ensured, and therefore the signal transmission quality and the bandwidth utilization rate are improved.
