Secrecy Outage Probability Fairness for Intelligent Reflecting Surface-Assisted Uplink Channel [PDF]
, 2022 This paper investigates physical layer security (PLS) in the intelligent reflecting surface (IRS)-assisted multiple-user uplink channel. Since the instantaneous eavesdropper's channel state information (CSI) is unavailable, the secrecy rate can not be ...

Outage Probability Analysis for Correlated Sources Transmission over Rician Fading Channels [PDF]
, 2013 In this paper, the outage probability of a Slepian-Wolf transmission system is analysed theoretically. We consider two correlated binary information sequences where bit-flipping model is adopted, where the the information bits of the second source are ...

Secrecy Outage Probability: Revisited.
CoRR, 2022 This paper technically explores the secrecy rate $Λ$ and a maximisation problem over the concave version of the secrecy outage probability (SOP) as $\mathop{{\rm \mathbb{M}ax}}\limits_{Δ} {\rm \; } \mathbb{P}\mathscr{r} \big( Λ\ge λ\big) $. We do this from a generic viewpoint even though we use a traditional Wyner's wiretap channel for our system model

Secrecy Outage Probability of Network-Coded Cooperative Communication
CoRR, 2014 We evaluate the secrecy performance of a multiple access cooperative network where the destination node is wiretapped by a malicious and passive eavesdropper. We propose the application of the network coding technique as an alternative to increase the secrecy at the destination node, on the top of improving the error performance of the legitimate ...

IET Communications, 2022 This paper investigates the impact of a dual‐signal selection (i.e. selection of direct signal and relay signal) and multiple eavesdroppers on secrecy outage probability in cooperative‐relay systems over Nakagami fading channels.

On Secrecy Outage Probability and Average Secrecy Rate of Large‐Scale Cellular Networks
Wireless Communications and Mobile Computing, 2018 We investigate the secrecy performance in large‐scale cellular networks, where both Base Stations (BSs) and eavesdroppers follow independent and different homogeneous Poisson point processes (PPPs). Based on the distances between the BS and user, the intended user selects the nearest BS as serving BS to transmit the confidential information.

IEEE Access, 2021 In this paper, we investigate secure communication in a hybrid relay (HR)-assisted wireless powered cooperative communication network (WPCCN), where an eavesdropper tries to intercept the data transmitted by a source user and the HR simultaneously.
