AbstractIn this paper, we propose a hybrid scheme called transmit antenna selection and receiver’s artificial noise (TAS–rAN) for security enhancement in multiple-input single-output (MISO) wiretap channels. In this scheme, by using TAS protocol, the transmitter selects a single antenna that maximizes the instantaneous signal-to-noise ratio (SNR) at the full-duplex receiver. While the transmitter uses this antenna to transmit secrecy data, the full-duplex receiver would send artificial noise (AN) to confuse the potential eavesdropper. For the proposed protocol, we consider Rayleigh fading channels with different parameters for the main channel and the eavesdropper’s channel, and derive new closed-form expressions for the exact secrecy outage probability and the asymptotic secrecy outage probability. We demonstrate that the proposed TAS–
