| 摘 要： | 差分跳频是一种新的扩展频谱通信技术.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码性能的检验方法,包括不可约性、频隙滞留、均匀性和随机性检验,其中频隙滞留是首次提出应用于差分跳频码性能的检验.这些检验方法对于差分跳频G函数的设计具有一定的指导意义.

| Abstract: | Differential frequency hopping(DFH) which comes down to a kind of G function algorithm is a new kind of spread-spectrum communication technique.Based on introducing the basic principle of DFH,the process of frequency hopping is modeled as a homogeneous Markov chain.The function of G functions is analyzed,and methods of testing the performance of DFH codes are discussed mostly.These methods,among which frequency slots lingering is put forward to test the performance of DFH codes for the first time,are valuable for designing DFH G functions. |
