Abstract

The present invention provides a satellite communication signal processing method, device, electronic equipment and medium. The method applied to ground terminals includes: receiving satellite pilot signals, extracting uplink working frequency bands; Frequency hopping uplink service signal; send frequency hopping uplink service signal to the satellite terminal according to the uplink working frequency band, so that the satellite terminal can de-hop the frequency hopping uplink service signal according to the frequency hopping pattern of the satellite terminal, obtain the de-hopping signal and send it to the gateway The restored local information decoded by the station is used as a signal processing result; the frequency hopping pattern of the ground terminal corresponds to the frequency hopping pattern of the satellite terminal. The present invention is applicable to the multi-satellite cooperative emergency communication system, and can increase the receiving gain and improve the reliability of the uplink during the communication process, especially the communication process under harsh conditions, and at the same time alleviate the terminal communication capability requirements and load storage pressure, and reduce the Hardware resource consumption.

Description

technical field [0001] The invention relates to the technical field of satellite communication, in particular to a satellite communication signal processing method, device, electronic equipment and medium. Background technique [0002] Natural disasters such as floods, earthquakes, and hurricanes and sudden public security incidents are likely to cause damage to the road-based communication network; at the same time, the surge in user communication demand after the disaster causes network congestion, and may even lead to communication interruption in the disaster area. Low-orbit satellite communication has the advantages of anti-damage, extensive coverage, backup and mobility, and plays an irreplaceable role in meeting the high-reliability communication requirements of rescue work in disaster areas and performing special communication support tasks. Satellite communication may be the only option for the complete paralysis of road-based and space-based communication networks ...
