差分跳频通信技术研究与延伸思考

Research on the Differential Frequency Hopping Technique and Further Thinking

近年来，差分跳频通信技术在国内引起了广泛关注。文章仿真实现了差分跳频通信系统，分析了差分跳频通信系统关键技术实现方法对系统性能的影响，基于对差分跳频技术的研究进行了延伸思考，论述了差分跳频技术的创新性及其和软件无线电的关系，展望了其在超短波频段的应用，并指出通信（通信对抗）装备研制中必须注意扩大装备的应用场景，体系架构和算法设计均需要有较强的环境适应性。

The differential frequency hopping （DFH） communication has been attached great attention at home and abroad in recent years. The DFH communication system is realized by simulation in this paper. The impact of the realization method of the core techniques of DFH, towards the system performance, is analyzed here. Based on the study of the DFH techniques, further thinking is given. The innovation of DFH is discussed, and the relation between DFH and software radio also. The DFH＇s application in V/UHF is prospected. It＇s also pointed out that much attention must be paid to enlarge the communication （communication countermeasure） equipment＇s application fields during the equipment＇ s development. Equipment＇ s architecture and algorithm should be of great environment accommodation.
