Research on resource allocation algorithm of multi-beam satellite communication signal

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.
