Frequency Tracking and Synchronization Strategy for Low Earth Orbit Satellites Based on Compensation and Prediction

Frequency Tracking and Synchronization Strategy for Low Earth Orbit Satellites Based on Compensation and Prediction

As an important supplement to the ground network, the low earth orbit (LEO) satellite network is an important component of the integrated network of space and earth. Due to the high moving speed of LEO satellites, a large Doppler frequency offset and its rate of change are caused, so a new frequency...
