| 摘 要： | 差分跳频是一种新的扩展频谱通信技术,它主要归结于一种G函数算法。本文在介绍差分跳频基本原理的基础上,将差分跳频的频率跳变过程建模成齐次马尔可夫链。分析了G函数的功能,重点讨论了差分跳频图案性能的检验方法;将常规跳频图案的一维均匀性检验进行了扩充,同时建议采用不可约性、频隙滞留检验,其中频隙滞留是本文提出应用于差分跳频图案性能的检验。

| Abstract: | Differential frequency hopping(DFH) is a new kind of spectrum spread communication technique owing to the G function algorithm.On the basis of introducing the basic principles of DFH,the process of frequency hopping is modeled as the homogeneous Markov chain.The functions of G functions are analyzed,and the methods of testing the performance of DFH patterns are discussed as the focal points.One-dimension uniformity testing is extended,irreducibility and frequency slots lingering are suggested.Frequency slots lingering is put forward to test the performance of DFH patterns. |
