Simulation and Analysis on Anti-Jamming Performance of Frequency-Hopping Communication System

Frequency-hopping communication is a main means of military communication, so it is very important to guarantee the normal work of this system in the complex communication environment. First, this paper introduces the theory of Frequency-hopping communication and the simulation of this system. Then, it analyses several common types of jamming in frequency-hopping communication, including broadband noise jamming, partial band noise jamming and tracking jamming. According to the pattern and feature of different jamming, it simulates different types of jamming by using Simulink software. At last, it gets the Bit Error Rate (BER) carves of system in different types of jamming by adding interference noises into the frequency-hopping communication system which has been set up. With the getting data and the BER carves, it analyses the anti-jamming ability of frequency hopping communication system under dif- ferent types of jamming, summarizes and proposes some improved methods.
