差分跳频利用频率的跳变携带信息
只要正确检测出每跳的频率
就可以恢复出信息.本文提出一种基于STFT的跳检测方法
并与G函数相结合来分析短波DFH信号在每跳时间间隔内的频率特性
以检测可能的跳频率.仿真结果表明
在短波信道几种可能的情况下
检测效果良好.
The information is carried through the hopping of frequency in DFH(Differential frequency hopping).If only the frequency is detected out
the information can be recovered.One method of hop-detecting based on STFT is put forward
and the frequency features of HF DFH signal in one-hop time is analyzed through it in this paper.Combining with the G function
it can detect the possible frequency.The simulation shows the detecting result is good in several kinds of HF channel.
