Secrecy Outage Probability and Fairness of Packet Transmission Time in a NOMA System

IEEE Access, 2020
In this paper, we analyze the secrecy outage probability (SOP) and the fairness of average packet transmission time for a non-orthogonal multiple access (NOMA) system which consists of a base station (BS) and two legal NOMA users in the presence of an ...

Cyber-Physical-Systems and Secrecy Outage Probability: Revisited

, 2022
This paper technically explores the secrecy rate $\Lambda$ and a maximisation problem over the concave version of the secrecy outage probability (SOP) as $\mathop{{\rm \mathbb{M}ax}}\limits_{\Delta } {\rm \; } \mathbb{P}\mathscr{r} \big( \Lambda \ge ...

On the ergodic secrecy capacity and secrecy outage probability of the MIMOME Rayleigh wiretap channel

, 2020
In this paper, we study the multiple-input multiple-output multiple-eavesdropper wiretap channel in the nonergodic and ergodic scenarios, both with stationary Rayleigh distributed fading channels.

Secrecy outage probability of two-path successive relaying in physical layer security

, 2016
Relaying is a promising technique to improve wireless physical-layer security. Existing literature shows that a full-duplex relay can further improve the secrecy capacity and secrecy outage probability compared to conventional half-duplex relay, but this
