Abstract

The present invention provides a method for scheduling resources based on beam hopping, which includes the following steps: dividing the satellite coverage area into multiple cells; dividing each cell into multiple rectangular units of equal size; representing each The actual channel capacity of the rectangular unit at different times; use the second three-dimensional matrix to indicate whether to serve each rectangular unit at different times, wherein element 1 of the second three-dimensional matrix indicates that the corresponding rectangular unit is served by hopping beams at a certain time, and element 0 Indicates that the corresponding rectangular unit is not served at a certain moment; the target matrix is ​​represented by the product of the first three-dimensional matrix and the second three-dimensional matrix; the second three-dimensional matrix is ​​adjusted so that the sum of all elements of the target matrix is ​​the largest; and according to the adjusted second The three-dimensional matrix serves the corresponding rectangular unit. Through this method, the allocation of beam-hopping beam resources in each satellite coverage area can be optimized for the scene of fast moving low-orbit satellites, so as to better schedule precious space resources.

Description

technical field [0001] The present invention generally relates to the field of satellite communication, and in particular relates to a method for scheduling resources based on beam hopping. Background technique [0002] In recent years, with the development of low-earth orbit satellite (LEO, low-earth orbit satellite) mobile communication technology, the low-earth orbit satellite communication service has attracted widespread attention due to its own advantages. With the continuous expansion of the country's strategic needs, people are no longer satisfied with the existing communication technologies on the ground, but focus on realizing the integration of space and ground, global coverage, multimedia satellite communication systems for personal mobile communication networks, low-orbit broadband Satellite networking communication technology is an important means to realize communication globalization and commercialization. However, due to the low orbit altitude and changing ...
