Performance evaluation of different jamming strategies over uncoded noncoherent fast FH/MFSK communication systems
04Sep_Karkatzounis.pdf (1013.Kb)Abstract
The fast frequency-hopping technique is considered one of the most effective Electronic Protective Measures (EPM) for military communications systems in order to mitigate the effect of a follower or repeat jammer. This thesis evaluates the performance of different jamming strategies as barrage noise jamming, partial band jamming and multitone band jamming against an uncoded noncoherent FFH/MFSK system with a conventional receiver. The theoretical and simulated results showed that the best jamming strategies for the examined modulation orders M=2,4,8 is the optimum case of multitone band jamming. As a second goal, this thesis also provides a preliminary analysis for an uncoded noncoherent FFH/MFSK system in a Rayleigh fading channel. This analysis includes the theoretical and simulated results for the influence in the performance from a barrage noise jammer along with AWGN. The results of the theoretical analysis and the simulation modeling for both cases can be used as guidelines to analyze more complicated jamming or combinations of jamming strategies against FFH/MFSK communication system.
