In this study a new jammer design for orthogonal frequency division multiplexing (OFDM) based systems is introduced. We present three new vulnerability attack scenarios based on chirp signals. These are the conventional chirp attack, the cyclic prefix chirp attack and the pilot tone chirp attack. Bit. error rate (BER) performances are investigated in presence of chirp based attacks. It is shown that the performance degradation is increased when compared to Gaussian distributed jammers Chirp signals are also preferable due to nominal peak-to-average power ratios (at least 7 dB lower than Gaussian counterparts).
