Satellite communication signal processing method and device, electronic equipment and medium

Abstract

The invention provides a satellite communication signal processing method and device, electronic equipment and a medium, and the method applied to a ground terminal comprises the steps: receiving a satellite pilot signal, and extracting an uplink working frequency band; converting the local information into a frequency hopping uplink service signal according to a ground terminal frequency hopping pattern; sending a frequency hopping uplink service signal to a satellite end according to the uplink working frequency band, so that the satellite end can de-hop the frequency hopping uplink service signal according to a satellite end frequency hopping pattern to obtain a de-hopped signal, and sending the de-hopped signal to a gateway station end to decode the de-hopped signal into restored local information as a signal processing result, wherein the ground end frequency hopping pattern corresponds to the satellite end frequency hopping pattern. The method is suitable for a multi-satellite cooperative emergency communication system, and can improve the receiving gain, improve the uplink reliability, relieve the terminal communication capability requirement and the load storage pressure and reduce the hardware resource consumption in the communication process, especially in the communication process under severe conditions.

Description

Technical field [0001] The present invention relates to the field of satellite communication, and more particularly to a satellite communication signal processing method, apparatus, electronic device, and medium. Background technique [0002] Natural disasters such as floods, earthquakes, and hurricanes are easy to cause roadbed communication networks; at the same time, users communicating demand surges cause network blocking, and may even lead to communication interruption in disaster area. Low-track satellite communication has advantages such as destroyability, wide coverage, backup, and mobile flexibility, and play an irreplaceable role in meeting the high reliable communication needs of the disaster area, performing special communication security tasks. For roadbeds caused by regional or even global natural disasters, the air-based communication network is fully paralyzed, and the satellite communication may be unique. Considering that the transmission power of the ground ter...
