摘要
跳频通信方式是军事通信的主要手段,保证跳频通信系统的正常工作十分重要,研究了跳频通信的几种常见干扰样式,用Simulink仿真工具搭建跳频通信系统仿真平台,并模拟几种常见干扰源,包括宽带或部分频带阻塞干扰、梳状阻塞干扰及跟踪干扰。分别在信道注入各种干扰,得到相应的误码率曲线,分析并评价其抗干扰性能。
Frequency-hopping is an important millitary communication means,and thus it is essential to maintain the normal operation of the whole system.This paper studies several common interference patterns in frequency hopping systems.A model for simulating a frequency-hopping spread spectrum system is constructed with Simulink tools,and several types of interference source are simulated,including broadband block interference,partial-band block interference,combing block interference,and tracking interference.Different types of interference are applied to the channel,thus to obtain the relative BER curves,analyze and evaluate the anti-jamming performance.
