Several modern digital wireless services, such as long-term evolution, relies on orthogonal frequency division multiplex (OFDM). OFDM is in general vulnerable to narrow-band interference such as continuous wave (CW). Earlier publications have indicated that this vulnerability is dependent on where in the OFDM-receiving frequency band the CW interference appears. In this paper, this frequency dependence is rigorously investigated and explained with both theoretical and numerical results. It is shown that by varying the CW frequency within a single OFDM subchannel, very large variations (several magnitudes, e.g., 10⁴ times) corresponding to bit error probability are obtained. This dependence in vulnerability is not considered in present radiated emission standards, and therefore a suggestion about how this could be handled is also presented.
