Abstract

The invention discloses a wave-hopping pattern optimization method and device based on a time slot allocation algorithm, and a storage medium, wherein the method includes the following steps: determining the distance threshold according to the calculated signal-to-interference-noise ratio SINR and the distance between beams; The relationship between capacity resources and time slot resources in the satellite system downlink constructs a time slot allocation model; obtains the requested capacity of users within the coverage of each beam, and converts the requested capacity into the number of requested time slots; for the number of requested time slots, The time slot allocation model is used to allocate the number of time slots for each beam, and the optimization of the beam hopping pattern is completed according to the principle of interference avoidance. By adopting the present invention, efficient time slot resource allocation can be realized in a geostationary earth orbit (Geostationary Earth Orbit, GEO) satellite communication system, and the influence of interference on signal quality can be effectively eliminated while improving system capacity.

Description

technical field [0001] The invention relates to the technical field of satellite resource allocation, in particular to a wave-hopping pattern optimization method and device based on a time slot allocation algorithm, and a storage medium. Background technique [0002] In recent years, with the continuous improvement of the service quality of satellite communication services, the demand for satellite communication services has gradually increased, but the power resources for carrying services and the bandwidth resources of transponders have become increasingly tight, which has led to an increasingly imbalanced supply and demand of satellite communication resources. protrude. In this context, the proposal and development of high-throughput satellites has opened up a new situation for solving this problem. High-throughput satellites can flexibly allocate power and bandwidth resources by introducing multi-port amplifiers, greatly increasing the available capacity of the system. ...
