| Considering that low Earth orbit satellites adopt beam hopping technology for full frequency multiplexing, exacerbating the degree of co-frequency interference in the system, thereby reducing the capacity of the system, a power allocation algorithm of beam-hopping system based on non-cooperative game is proposed in this paper. First, a power resource allocation model based on non-cooperative game is established, and an alternate iterative algorithm is proposed to solve the Nash equilibrium. Then, OPNET is used to build a system-level simulation platform, and the performance of the power allocation algorithm is effectively evaluated. The simulation results show that the proposed power allocation algorithm achieves obvious improvement in interference suppression, spectral efficiency and fairness compared with water filling algorithm and power squaring pricing game. |
