摘要
Abstract
LEO satellites have superior development prospects due to their low cost,low latency and small path loss,and are widely used in IoT,B5G and other fields.For the LEO satellite and its coverage area will be in a moving state,a convex optimization-based long-time multi-star beam hopping power allocation algorithm was proposed to maximize the system capacity.Focused on the multi-star hopping beam scenario over a period of time,a system model was developed based on the long-time co-orbital multi-star hopping beam scenario and the long-time heterodyne multi-star hopping beam scenario respectively.The resource allocation algorithm was designed for the two long-time multi-star hopping beams with the weighted objective function as the optimization objective,considered the in-fluence factors of inter-star interference,load balancing and inter-star resource allocation priority,a long-time skipping beam resource allocation algorithm based on convex optimization was proposed.The simulation results showed that the proposed scheme could im-prove the resource utilization of the system compared with the conventional schemes.关键词
