Artificial-Noise-Aided Secure Transmission in Wiretap Channels With Transmitter-Side Correlation

Yan, Shihao; Yang, Nan; He, Biao; Zhou, Xiangyun; Abhayapala, Thushara


This paper, for the first time, examines the impact of transmitter-side correlation on the artificial-noise (AN)-aided secure transmission, based on which a new power allocation strategy for AN is devised for physical layer security enhancement. Specifically, we design a correlation-based power allocation (CPA) for AN, of which the optimality in terms of achieving the minimum secrecy outage probability is analytically proved in the large system regime with the number of transmit antennas...[Show more]
