Analysis on Anti-jamming Performance of Simulink-based Frequency Hopping Systems

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.
