Abstract
Aiming at the problem of limited communication bandwidth between satellite and ground station, combining the communication scenario between satellite and ground station, the forward and backward link margin is analyzed, and a bandwidth adaptive communication method based on software defined radio is proposed, which dynamically adjusts the forward and backward link bandwidth according to the signal-to-noise ratio of the actual received signal from satellite and ground station. By this method, the waste of link resources is avoided, and the channel capacity is maximized. Finally, the transmission capacity in the measurement and control arc section of the ground station will be improved. The simulation results show that the transmission capacity of the proposed method is 2–3 times higher than that of traditional method.
