Technical Field

Background
With the development of satellite communication technology, the service types supported by the satellite communication terminal are more and more, including voice, fax, short message, IP data and the like, and the communication bandwidth is more and more large. Satellite communication is not limited by geographical environment and flexible to use, and is an important supplementary communication means of a land mobile communication system. The need for effective supervision and management of satellite communications is also becoming increasingly urgent. In satellite communication, in order to improve the frequency use efficiency and reduce the terminal volume, a spot beam system is adopted, and the spot beam diameters of different satellite communication systems are generally in the range of 400 km to 1200 km. When the satellite communication system is controlled, interference control is sometimes required to be performed on terminal communication in a cross-beam in order to improve the control range. Since only the beam isolation can be estimated approximately, the actual environment is also affected by the specific position of the beam where the communication terminal is located, and the deviation from the estimated value may be large. When the conventional method is used for cross-beam interference management and control, interference is mainly carried out with larger fixed power, isolation influence of adjacent beams is counteracted, the situation that interference power is overlarge or interference power is insufficient often exists, actual interference effect is poor, and overall efficiency is low. Therefore, the self-adaptive distribution method for the satellite communication multi-beam interference power is provided, so that the interference power is controlled in a self-adaptive and accurate mode, the isolation influence of adjacent beams is counteracted, and the interference efficiency is improved.
