摘要
文章介绍了一种新型的短波跳频通信技术——差分跳频,分析了差分跳频技术区别于常规跳频技术的主要特点。针对按序列检测的信号接收方法,对差分跳频通信系统在AWGN信道下的性能进行了理论分析,同时做出相应的计算机仿真,证实了差分跳频通信技术和按序列检测方法的结合,使通信系统在AWGN信道下的性能得到了比较显著的提升。
A new HF hopping system, which is called Differential Frequency Hopping （DFH） system, is presented in this paper. The main difference between DFH and traditional Frequency Hopping （FH） is induced detailedly. The performance of DFH system in AWGN channel with detection by sequence is analyzed in theory, and the corresponding simulation results are given. All these prove that the performance of DFH system with signal detection by sequeuce is much better than ordinary frequency hopping system in AWGN channel.
