差分跳频组网及其特性分析

The Making-Up of Differential Frequency Hopping(DFH) Network with Its Characteristics

本文在阐述短波差分跳频原理的基础上,首次提出了差分跳频组网所需要的参数种类,重点分析了其组网方式,扩展了跳频同步组网的定义范围,并重点对差分跳频异步组网性能进行了相应的理论推导,利用概率统计的方式,探讨了差分跳频异步组网的网间多址干扰概率与组网数的关系,研究了异步组网效率与网间多址干扰概率的关系,得出了一些有益的结论.

Based on the principle of high frequency（HF）DFH, this paper preliminarily proposed the classification of parameters for the first time, which DFH network make-up needed, studied its network make-up method, extended implication of synchronous frequency hopping network make-up, and paid emphases on the derivation of the theoretical characteristics of the network making-up asynchronously by taking the method of statistics, discussed the relationships between the multiple-access interfere probability and the numbers in a asynchronous DFH network, as well as with the corresponding relationships between the efficiency and the multiple-access interfere probability, then obtained some good conclusions finally.
