摘要：
For the secure wireless communication of the proximal desired receiver user and the eavesdropper, i.e., channels of the legitimate user and the eavesdropper are highly correlated, a physical-layer security wireless transmission synthesis based on frequency diverse arrays is proposed. Firstly, for the physical layer security problems for knowing locations of the eavesdropper, the optimal frequency in the crement across transmit element is obtained by the adaptive genetic algorithm to maximize the secrecy capacity. And then the artificial noise and the design projection matrix are added to reduce the signal-to-noise ratio of the eavesdropper user. Furthermore, the proposed approach is extended to the case of the unknown location of the eavesdropper. Finally, numerical results show that the proposed method can provide the satisfactory secrecy capacity. © 2020, Editorial Office of Systems Engineering and Electronics. All right reserved.
