Secrecy Outage Performance Analysis for Cooperative NOMA Over Nakagami- $m$ Channel

open access: yesIEEE 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.

Performance Analysis of Secret Precoding-Aided Spatial Modulation With Finite-Alphabet Signaling

open access: yesIEEE 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

On the Secrecy Performance of Mixed RF/UOW Communication System [PDF]

open access: yes2018 IEEE Globecom Workshops (GC Wkshps), 2018
In this paper, the secrecy performance of a dual-hop mixed radio-frequency/underwater optical wireless communication (RF/UOWC) system is investigated. The considered system consists of one single antenna source node ($S$) communicating with one destination node ($D$), considered as the legitimate receiver, through the help of one amplify-and-forward ...
