To Establish a Secure Channel from a Full-duplex Transmitter to a Half-duplex Receiver: An Artificial-Noise-Aided Scheme

This letter considers a new secure communication scenario where a full-duplex transmitter (Alan) needs to transmit confidential information to a half-duplex receiver (Bob), with an eavesdropper (Eve) that tries to overhear the confidential information. For realizing the secure communication, we design an effective artificial-noise-aided secure scheme (ANAS) which is composed of two phases' transmi...
