In this paper an investigation to the performance of a single input single output orthogonal frequency division multiplexing (OFDM) system in additive white Gaussian noise (AWGN) channel in the presence jamming is provided. The effect of different types of jamming techniques such as the traditional noise jamming schemes (presented by barrage band,
partial band and pulsed jamming) and waveform jamming (matched jamming signal) is investigated on the performance of OFDM communication systems. Two novel jamming schemes are proposed (the first is a noise jamming technique and the second is a waveform jamming technique). The performance of the two proposed jamming schemes is compared
with the previously mentioned jamming techniques. It will be shown that the two proposed jamming schemes outperforms the other traditional jamming techniques. Also, it will be shown that the proposed waveform jamming scheme is more efficient than the proposed noise jamming one. Yet, the latter outperforms in the issue of cost and complexity.
