Analysis and simulation of typical mode of jamming on data link communication system

The anti-jamming technical development of communication system promotes the jamming technical development of communication system. The four typical modes of jamming on data link communication system (DLCS) such as noise amplitude-modulation (AM) jamming, noise frequency-modulation (FM) jamming, random binary-code modulation jamming and pseudo-noise (PN) code MSK modulation jamming were introduced. The mathematical expressions of them were also given out. Their jamming characteristics were analyzed. Based on that, the simulation models of the above-mentioned four typical modes of jamming based on Simulink in Matlab were developed. And then their jamming characteristics can be shown by use of simulation. The model can be applied in the anti-jamming performance analysis and simulation of DLCS.
