Secrecy Outage Performance Analysis for Cooperative NOMA Over Nakagami-
IEEE Access, 2019 In this paper, we investigate the secrecy outage performance of a typical cooperative downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel, in which the base station transmits a superimposed signal to two users via a relay.

Optimal Power Allocation by Imperfect Hardware Analysis in Untrusted Relaying Networks [PDF]
, 2017 By taking a variety of realistic hardware imperfections into consideration, we propose an optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a cooperative wireless network comprised of a source, a destination and an ...

Secrecy performance of terahertz wireless links in rain and snow [PDF]
Nano Communication Networks, 2021 Wireless communication technique at terahertz (THz) frequencies is regarded as the most potential candidate for future wireless networks due to its wider frequency bandwidth and higher data capacity when compared to that employing radio frequency (RF) and millimeter wave (mmWave).

Performance Analysis of Secret Precoding-Aided Spatial Modulation With Finite-Alphabet Signaling
IEEE Access, 2018 The precoding-aided spatial modulation (PSM) is first characterized with respect to its secrecy performance, which shows that the PSM is a secrecy embedded communication scheme when operated in the time-division duplex mode, but experiences security risk

Source-Channel Secrecy with Causal Disclosure [PDF]
, 2012 Imperfect secrecy in communication systems is investigated. Instead of using equivocation as a measure of secrecy, the distortion that an eavesdropper incurs in producing an estimate of the source sequence is examined.
