摘要

Spectrum efficiency and energy efficiency are important performance indicators of the MIMO satellite injection system. However, maximizing EE and SE is a pair of conflicting goals, and it is difficult for both to achieve the optimal at the same time. This paper studies the joint optimization problem of EE and SE in a single-station multi-satellite MIMO injection system, and proposes a knee-point driven EE-SE optimization algorithm. By guiding the evolution direction of the genetic algorithm through the knee points, the transmission power of the base station can be reasonably allocated without clear preference by the decision maker, and the joint optimization of EE and SE can be realized. The simulation results show that the algorithm has good performance in the optimization of EE-SE.
