| Abstract(in English) | We analyze the performance of a secure communication technique using OFDM and DFT-precoded OFDM signaling. Our approach is based on a wireless steganography where DFT-precoded OFDM is used as a cover signal and embedded secret data is carried by the superposed OFDM signal. This work theoretically analyzes the performance of a warden who attempts to detect the existence of the embedded signal in terms of his detection probability, and studies the symbol error rate achieved by a legitimate user through computer simulations where the communication channel is modeled by a practical frequency selective Rayleigh fading channel. |
