摘要
差分跳频通信是一种全新的跳频体制,差分跳频是CHESS电台的核心技术,它主要归结为一种信息调制于一体的频率转移函数(G函数)算法。在深入研究了频率转移函数产生机理及构造特性基础上,通过在隐式中引入纠错能力很强的RS码来控制跳频子集,从而提出了一种优化的针对1bit数据传输的G函数的正、逆构造算法并对其进行检验。结果表明,该算法产生的跳频图案具有良好的随机性和均匀性.
Differential frequency hopping（DFH） is a new frequency hopping spread spectrum.A key concept in CHESS design is the use of a differential frequency hopping technique,which mainly is an algorithm of frequecy converter function（function G）,which merges information modulation and frequency hopping patterns together.Based on principle of function G,RS code which takes on better modification capability control subset of frequency hopping.In this paper,we present to use a new method to improve frequecy performance.The patterns are analyzed and tested.The results show that frequency hopping patterns generated by the new algorithm have better randomicity and uniformity.
