At present, the satellite signal resource allocation strategy does not consider the coupling relationship between power and bandwidth. At the same time, due to the use of multi-beam antenna and frequency reuse techniques in satellite communication systems, the co-channel interference of inter-beam signals is a factor that should be considered. And Satellite systems have to deal with many real-time signal transmissions, and the limitation of transmission requirements on delay is also a consideration. Considering these factors and different signal transmission conditions between beams, a new satellite signal resource allocation algorithm is proposed by reconstructing the satellite system model. The simulation results show that the new algorithm improves the system capacity and reduces the second-order service rejection of the system while comparing with the previous resource allocation algorithm. |
