The beam-hopping technology can solve the problems of uneven user distribution and uneven service demand and improve the efficiency of resource utilization. It is one of the important technologies of future satellite–ground integrated communication. However, the mobility of LEO satellites and the on-demand scheduling of beams make each satellite beam correspond to multiple ground wave positions, which brings great difficulties to data processing. In this paper, after analyzing the difficulties of the data forwarding buffer of the beam-hopping system, a double-linked list structure of user state chain and data buffer chain is proposed, which solves the problem of data forwarding between the satellite and users in the dynamic state and provides an efficient solution for the data exchange of the beam-hopping LEO satellite.

LEO卫星跳束转发缓冲双链表设计

跳束技术可以解决用户分布不均匀、服务需求不均匀的问题，提高资源利用效率。它是未来星地一体化通信的重要技术之一。然而，低轨卫星的移动性和波束的按需调度使得每个卫星波束对应多个地波位置，这给数据处理带来很大困难。本文在分析了波束跳变系统数据转发缓冲区的难点后，提出了一种用户状态链和数据缓冲区链的双链表结构，解决了卫星与用户之间的数据转发问题。动态状态，为跳波LEO卫星的数据交换提供了有效的解决方案。
