Abstract
In this paper, a secure communication system based on fractional Fourier transform (FrFT) is proposed. Information data is encrypted by a certain order FrFT at transmitter, and then divided into two parts and sent out. The receiver decodes the signal using FrFT with the corresponding order to the transmitter to obtain the original data. Simulation results demonstrate the effectiveness of the proposed secure communication system, and the bit error rate for the signals without decryption remains large even for high signal-to-noise ratio.
