초록
Efficient frequency reusing schemes with multibeam satellite systems can be considered as a promising means of providing high-quality services with expensive and limited satellite bandwidth resources. This letter considers integrated satellite and terrestrial systems, where the same frequency bands are reused in the satellite beams and terrestrial cells. In such a condition, we propose an efficient power and frequency resource allocation scheme to minimize inter-component interference while the maximum throughput is provided to the users. The proposed scheme consists of two simple linear machine learning-based tools and a linear transformation tool. The simulation results show that the proposed scheme approximates the exhaustive search with a highly reduced complexity.
