摘要
跳频通信技术具有较强的抗干扰能力,因此一直是扩频通信技术研究中的一个重点。在阐述跳频通信基本原理和实现方法的基础上,利用Matlab提供的可视化工具Simulink建立了跳频通信系统仿真模型,详细讲述了各模块的设计。在给定仿真条件下,对该跳频通信系统在宽带噪声干扰工作机制下进行了仿真,得到了在宽带噪声干扰下的误码率-信噪比曲线。结果表明,跳频通信系统的抗干扰能力优于传统的定频通信,在战术通信中有更高的可靠性。此外还提出了提高跳频通信对抗宽带噪声干扰能力的改进方法,它对研究跳频通信系统抗干扰的性能具有借鉴作用。
Frequency-hopping communication technology is an emphasis in the research of the spread spectrum communication technology, which has good anti-jamming performance. The simulation model of frequency-hopping communication system is built by using SIMULINK provided by Matlab, based on the basic principle and realization methods of frequencyhopping communication. In addition, each module of the simulation model is introduced in detail. In light of full-band noise jamming system, the simulation program is run on the basis of the designed simulation conditions, BER-SNR curve figures are gained. The results show that the frequency-hopping communication system has better ability of anti-jamming than the traditional fixed frequency communication, and is of even higher reliability in tactical communication. An improved method for the enhancement of full-band noise anti-jamming capability of frequency-hopping communication is proposed.
