Abstract :
The directional modulation is a prominent and practical technique for enhancing the physical layer security in modern communication systems. In this method, the message signal is modulated by an array of antennas and transmitted in a specific direction to the legitimate receiver, such that in other directions, the signal is destroyed and not receivable by eavesdroppers. By incorporating random frequency diverse array directional modulation, secure communication can be achieved in both angular and distance dimensions for the legitimate receiver. However, when the eavesdropper is located near the legitimate receiver, the confidentiality performance of this solution significantly deteriorates. To address this issue, this paper proposes a novel approach that combines artificial noise with random frequency diverse array directional modulation and optimizes power allocation to attain the maximum secrecy rate. Simulation results demonstrate that our proposed approach improves the secrecy rate of the physical layer security by at least one bit per second per hertz compared to the method without artificial noise, and by at least two bits per second per hertz compared to the phased array directional modulation.
