Özet
In this article, the accomplishment of OFDM systems under different jamming attacks is analyzed. Partial band jamming signal suppressing OFDM data packets partially and full band jamming signal suppressing all OFDM data packets are examined in this study. Computer simulation works are carried out to analyze the achievement of the OFDM system over AWGN and frequency selective Rayleigh fading channels under both jamming attacks. In addition, comparative performance analysis of different equalizer structures in frequency selective Rayleigh fading channel environment is performed. From the obtained results, it is seen that frequency domain equalizers combat jamming attack signals in the best way and provide the best performances.
