Journal ArticleDOI
On the Design of Secure Non-Orthogonal Multiple Access Systems
TL;DR: In this article, a non-orthogonal multiple access (NOMA) system with secrecy outage and QoS constraints is considered and the optimal decoding order, transmission rates, and power allocation to each user is investigated.
Journal ArticleDOI
Delay-Intolerant Covert Communications With Either Fixed or Random Transmit Power
TL;DR: The examination of delay-intolerant covert communications in additive white Gaussian noise channels with a finite block length shows that the amount of information that can be covertly transmitted logarithmically increases with the number of random power levels, which indicates that most of the benefit of using random transmit power is achieved with just a few different power levels.
Journal ArticleDOI
On Covert Communication With Noise Uncertainty
TL;DR: New metrics for measuring the covertness are defined and adopted to analyze the maximum achievable rate for a given covertness requirement under both bounded and unbounded noise uncertainty models.
Journal ArticleDOI
Secure On-Off Transmission Design With Channel Estimation Errors
Biao He,Xiangyun Zhou +1 more
TL;DR: This paper designs secure on-off transmission schemes to maximize the throughput subject to a constraint on secrecy outage probability and shows how the optimal on- off transmission thresholds and the achievable throughput vary with the amount of knowledge on the eavesdropper's channel.
Journal ArticleDOI
Artificial-Noise-Aided Secure Transmission in Wiretap Channels With Transmitter-Side Correlation
TL;DR: In this paper, the authors examined 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.
