Abstract

The invention discloses a hopping pattern optimization method and device based on a time slot allocation algorithm, and a storage medium. The method comprises the following steps: determining a distance threshold according to a relationship between a calculated signal to interference plus noise ratio (SINR) and a distance between beams; constructing a time slot allocation model according to the relationship between the capacity resources and the time slot resources in the downlink of the hopping beam satellite system; obtaining the request capacity of a user in each beam coverage range, and converting the request capacity into the number of request time slots; and for the number of request time slots, adopting a time slot allocation model to allocate the number of time slots for each beam,and completing optimization of a hopping beam pattern according to an interference avoidance principle. By adopting the method and the device, efficient time slot resource allocation can be realizedin a GEO (Geosynchronous Orbit) satellite communication system, and the influence of interference on signal quality is effectively eliminated while the system capacity is improved.

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. ...
