Satellite signal demodulation method, device, equipment and medium

The invention discloses a satellite signal demodulation method and device, equipment and a medium. The method comprises the following steps: acquiring a current satellite signal and current adjustment parameter information at a current moment, wherein the current adjustment parameter information comprises a demodulation gain parameter, a first optimization gain parameter and a filter coefficient; and performing channel energy sensing and signal demodulation on the current satellite signal based on the current adjustment parameter information, and determining the next adjustment parameter information at the next moment and the demodulated current data frame. The demodulation gain parameter, the first optimization gain parameter and the filter coefficient are determined in the downlink time slot by adopting channel energy perception, and the capture of the synchronization head and the frame demodulation decoding are completed in the downlink time slot to obtain the current data frame, so ...
