Systems and methods for securing orthogonal frequency division multiplexing (OFDM) transmission of data are discussed herein. Transceivers can sense the signal strength of frequencies on an OFDM wireless channel. The transceivers can determine which of the frequencies are fading frequencies failing below a threshold. A transmitting transceiver can send artificial data on the failing frequencies and genuine data on the remaining frequencies. Artificial data can be designed to mitigate peak-average-power ratio (PAPR) to have an additional benefit without using extra resource. Finally, receiving transceiver can transceiver receive the genuine data while discarding any date received on the failing frequencies.
