摘　　要：直序列扩频与跳频扩频在实际中最常用的两种扩频信号。文章介绍了基于跳频(FH)信号通信系统抗干扰的基本原理。借助MATLAB仿真软件,采用MFSK调制方式,在宽带干扰、不同比例的部分频带干扰条件下,对不同跳频速率的系统性能进行仿真。通过分析仿真结果,较好的说明了跳频信号通信系统的优点,最后给出了提高跳频系统抗干扰能力的相应措施。DS and FH are the most common forms of spread spectrum signals used in practice.In this paper,the basic anti-jamming principle of the FH-based communication system is introduced.By using MATLAB,we have simulated the performance of different FH rates in the presence of broadband interference or partial-band interference.Through analyzing the simulation results,we show the benefits obtained from FH communication system.Finally,We provide the corresponding means for improving its anti-jamming performance accordingly.
