Abstract
To enhance the physical layer secure of wireless communication, we in this paper proposeda simple secure wireless communication mechanism based upon multiple weighted type fractional Fourier transform (M-WFRFT). We firstly provide the definition of M-WFRFT and two important theorems. Moreover, the secure wireless communication system is proposed with different secret keys between transmitter and receiver. And also the frame structure designation is exploited in this paper. The performance of the proposed secure wireless communication system is verified by some numerical simulations. It can be demonstrated, from the numerical simulations, that the proposed secure wireless communication mechanism can effectively avoid communication information leaking even if the eavesdropper intercepts transform information of transmitter.
