| 摘 要： | CHESS电台采用了差分跳频技术,可以实现短波频段内高速率数据传输。在分析差分跳频信号的生成过程以及对信号进行检测的原理的基础上,构建了差分跳频通信系统仿真模型,对AWGN信道和Rayleigh信道下差分跳频信号与常规跳频信号的抗多音干扰能力进行了仿真分析。结果表明,差分跳频信号具有较强的抗多音干扰能力。

| Abstract: | The CHESS radio which make use of differential frequency hopping technology helps to achieve high-rate data transmission in HF band. Based on analysis on the DFH sequence generation and DFH signal detection principles,the simulation model for DFH system is establised. The ability of DFH and conventional HF signals against multitone jamming under the AWGN channel as well as Rayleigh channel are simulated and analyzed. The results show that DFH system has strong performance against multitone jamming. |
