摘　　要：为满足差分跳频通信在短波电台上的模块化和结构化应用需求,在深入研究G函数和FFT宽带接收机理基础上,基于同余理论G函数设计了差分跳频信号产生模块,基于加窗FFT设计了频点序列识别模块,采用频差译码设计了G-1函数解析模块。基于FPGA平台对差分跳频通信关键模块进行了仿真实现。仿真和测试结果表明,设计的模块完成了差分跳频信号的无线收发,实现了差分跳频通信功能。采用模块化结构化的设计,提高了差分跳频通信设备灵活性,易于升级维护。In order to meet the modular and structure design demand of the Differential Frequency Hopping（DFH） communication in short wave radio station,in-depth study of G function and FFT broadband receiver mechanism,DFH signal generation module has been designed based on Congruences G function theory,frequency sequence recognition has been designed based on windowed FFT,and G-1 function analysis module has been designed by using frequency differential decoding.Simulation and test results of the key modules based on FPGA platform show that the designed module can fulfill DFH signals wireless transceiver and realize communication function of the DFH.Meanwhile,the design of modular and structure can enhance the flexibility of the DFH communication equipment,which is easier to upgrade and maintenance.
