摘要
分析了跳频通信系统的组成模块、工作原理及系统特点,模拟建立了跳频通信系统模型,在Simulink中建立了仿真模型,通过设置合理的参数真实的模拟了跳频通信系统。实验结果表明,所设计的跳频通信系统,抗干扰性较好,信噪比较高,误码率较低,能较准确的恢复信源端信息,为未来跳频通信技术的革新提供了前期的研究基础。
The building blocks of frequency hopping systems, working principle and the main features were analyzed and modeled for communication systems. The system simulation model in Simulink is set up, therefore, the frequency hopping communication system was realistically simulated by setting reasonable parameters. The result showed that it has the strong anti-jamming capability, higher signal to noise ratio and low error rate, the source-side information was more accurately restored, providing preliminary research for hopping communications technology of the future innovation.
