Feature Suppression for Physical-layer Security in OFDM Systems
OFDM symbols carry redundancy due to the cyclic extension employed for providing immunity to multipath distortion. This redundancy can be used for blindly detecting the transmission parameters as well as achieving synchronization to transmitted signal. This paper proposes transmission-level techniques for suppressing physical-layer features of OFDM waveform. Hence, a covert, secure and reliable transmission based on OFDM technique can be achieved. We analyze the effectiveness of the proposed methods by investigating the cyclic autocorrelation function (CAF) of the OFDM waveforms.
