AI Technical Summary

Technical Problem

Existing satellite-to-ground network resource allocation methods rely on static preset strategies and dynamic local optimization mechanisms, resulting in uneven resource utilization, delayed response in high-dynamic scenarios, severe co-channel interference, and spectrum competition issues.

Method used

A three-dimensional decision matrix is ​​constructed and encoded as chromosome individuals. Based on the fitness function, optimization is performed to generate a target resource allocation scheme, considering total interference, channel utilization, and communication quality loss, while satisfying the constraints of the communication angle, propagation loss, and channel conflict.

Benefits of technology

It achieves balanced, efficient, and low-interference resource allocation in highly dynamic satellite-to-ground network scenarios, solving the problems of uneven resource utilization and severe co-frequency interference.
