Research And Simulation On The Jamming Of Frequency-Hopping Communication System

Frequency Hopping Spread Spectrum (FH-SS) communication is widely used, especially in the field of military communication, because of its better ability in anti-interference and net-working, so reconnaissance and jamming signals of FHSS system are considered as important contents in communication counter measures Based on the project, theoretical analysis and simulation on jamming performance of FH communication system were shown in this paper.This paper introduces FH communication principle including structure, mathematic model, primary technical parameters. Especially, jamming performances are analyzed and simulated. It concludes the effect which makes to FH communication system from typical jamming on the theoretical point, including full-band noise jamming, partial-band noise jamming, single frequency jamming, multiple frequency jamming and track jamming. Moreover, bit-error-rate (BER) calculations of FH/BFSK system are presented under above jamming conditions. The simulation model of FH communication system is built on the Matlab/Simulink software platform and every jamming model is built which contains. BER-JSR curve figures are presented under above jamming conditions as changing the parameters of the jamming mode and validate the theory analysis.
