中文摘要
星地融合网络在军事通信、情报侦查、应急通信与环境监测等领域得到越来越广泛应用,由于卫星传输的广域性、无线传播环境的开放性和用户终端的移动性等因素使得星地融合网络面临着严峻的安全威胁。本项目基于无线信道物理层链路的特性,开展星地融合网络中的安全通信理论和方法研究。首先,建立星地融合网络安全通信系统模型并对非理想的网络传输节点进行研究;接着,设计基于门限的中继选择算法,结合实现复杂度,遴选出合适的中继选择算法;再其次,根据具体应用场景并结合中继转发器特性,研究双向中继转发策略,设计缓存中继策略,提出多用户调度安全传输策略;最后引入非正交多址接入技术,研究星地融合网络资源优化策略,通过凸优化方法完成系统的最优功率分配,使系统达到最佳安全性能。通过本项目研究,可深化星地融合网络中物理层安全通信理论,探索适合星地融合网络的物理层安全传输方法,对物理层安全技术在星地融合网络中的研究和应用具有重要意义。
英文摘要
Integrated satellite terrestrial relay networks (ISTRNs) are widely exploited in military communication and backhaul scenarios, such as communication and environmental monitoring, due to broadcasting of the satellite, the openness of the wireless propagation environment and the mobility of the user terminal, secure transmission in the ISTRNs have aroused extensive research interests from both industry and academia. Firstly, we establish the secrecy transmission model and investigate the imperfect network nodes for the ISTRNs. Secondly, we propose the relay selection schemes based on the scheduling threshold. Taking the complexity for the important index, we chose the most suitable selection scheme. Thirdly, with the help of practical scenarios and terrestrial relays’ forward characters, we investigate the impact of two-way relay and design the scheme for the buffer-aid terrestrial relay. In addition, we propose the scheduling scheme for the multiple users of the ISTRNs and investigate the secrecy performance. Finally, by utilizing the non-orthogonal multiple access technology, we investigate the allocation problem for the resource of the ISTRNs. In order to obtain a better secrecy system performance, we try to find the optimal allocation factors versus convex optimization technology. By the research of this project, the secrecy transmission theory of the ISTRNs is investigated deeply. It is of great significance for the research and application of physical layer security technology in ISTRNs to explore the suitable physical layer secure transmission method for ISTRNs.
