摘 要:差分跳频(DFH)是一种新的短波跳频技术,它主要归结为一种G函数算法,这种G函数集跳频图案、信息调制与解调于一体。它的通信机理与常规跳频完全不同,较好的解决了数据速率和跟踪、干扰等问题,代表了当前短波通信的一个重要发展方向。鉴于此,在研究G函数算法原理的基础之上,重点对短波差分跳频信号的发生器进行基于FPGA的整体优化设计,并在软件和硬件环境下进行仿真与实现,从而指导工程实践。Differential frequency hopping(DFH) is a new shortwave frequency hopping technology,which mainly comes down to a G function algorithm that combines frequency hopping(FH) pattern,information modulation and demodulation into a whole.Its communication mechanism is completely different from the conventional frequency hopping,can successfully deal with the issues such as transmission speeds,tracking,jamming,and represents an important development direction of current shortwave communications.As a result,based on the study of G function algorithm principle,a differential frequency hopping signal generator based on FPGA has been optimization designed,and the simulation and implementation in the environment of software and hardware have been carried out so as to guide the engineering practice.
