Secrecy Outage Performance of SWIPT Cognitive Radio Network With Imperfect CSI
IEEE Access, 2020 We consider a cognitive radio (CR) network with simultaneous wireless information and power transfer (SWIPT) system having one base station (BS) with multiple antennas that acts as a secondary transmitter, one desired information receiver (IR) acting as ...

Physical Layer Security in Cognitive Untrusted Relay Networks
IEEE Access, 2018 In this paper, we consider the secure communications in a cognitive untrusted relay network, where the secondary source intends to communicate with a secondary destination through an untrusted relay in the presence of the direct source-destination link ...

On the Zero-Outage Secrecy-Capacity of Dependent Fading Wiretap Channels
, 2022 It is known that for a slow fading Gaussian wiretap channel without channel state information at the transmitter and with statistically independent fading channels, the outage probability of any given target secrecy rate is non-zero, in general.

Secrecy Outage Analysis of Mixed RF-FSO Systems With Channel Imperfection
IEEE Photonics Journal, 2018 We analyze the secrecy outage performance of a mixed radio frequency-free space optical (RF-FSO) transmission system with imperfect channel state information (CSI). We deal with a single-input multiple-output wiretap model, where a base station (works as
