摘要

传统的多波束卫星由于固定带宽而不能适应变化的业务流量，不能针对流量负荷进行动态调整，未来多波束宽带卫星系统必须具有较大的灵活性，能够根据业务流量的变化进行动态调整，其中跳频多波束宽带卫星网络系统改善了传统的多波束宽带卫星网络系统性能，而随着认知无线电技术的发展，认知跳频多波束宽带卫星可以进一步提升频谱的利用效率，此外，软件定义网络技术也在卫星网络中得到应用，可以实现对卫星资源的有效管理，提高卫星资源的利用率。探讨了软件定义认知跳频多波束宽带卫星网络系统的原理，分析频谱利用效率，建立吞吐量等业务模型，进行仿真分析，可作为宽带卫星网络系统设计的参考。

Abstract

Traditional multi-beam satellites cannot adapt to the changing traffic because of the fixed bandwidth and cannot adjust dynamically for the traffic load.In the future

the multi-beam broadband satellite system must have great flexibility and can be dynamically adjusted according to the change of the traffic flow.Beam hopping for multi-beam broadband satellite network system has been proposed to improve the traditional multi-beam broadband satellite network system performance

whose principle is to assign different beams to different time slots

rather than the allocation of bandwidth

so that in each time slot

the entire available bandwidth is allocated to each beam

and the time window is periodically applied to the beam selection system

in the full band hopping mode

the band can be selected optimally in the duration of each beam to meet user transmission bandwidth and delay requirements.With the development of cognitive radio technology

cognitive beam hopping for multi-beam satellite system can further improve the efficiency of spectrum utilization

to meet the growing shortage of spectrum resources

to achieve large-capacity high-bandwidth broadband satellite network system

and to support the rising user service capacity and the transmission efficiency of user services under different load conditions.In addition

software definition technology is also used in satellite networks

which could achieve effective management of satellite resources to improve the utilization of satellite resources.In this paper

the principle of software-defined cognitive hopping multi-beam broadband satellite network system is discussed.The spectrum utilization efficiency and throughput are analyzed

which can be used as a reference for broadband satellite network system design.
