AI Technical Summary
In existing wireless secure communication technologies, the complexity of radio frequency end optimization methods is high, while the energy utilization rate of baseband based on artificial noise is low, making it difficult to achieve efficient and secure communication.
By utilizing the amplitude characteristics of OAM, communication is achieved through multi-element phased array antennas of both the transmitter and receiver. The transmitter's transmission radius is adjusted to generate a beam peak at the location of the legitimate user, thereby reducing the signal energy of eavesdroppers and enabling secure communication.
It achieves secure communication without the need for complex optimization calculations or the addition of artificial noise, reducing communication complexity and improving communication security.
