Secrecy Performance Analysis of SIMO Systems over Correlated κ-µ Shadowed Fading Channels [PDF]

open access: yes, 2019
In this paper, the secrecy performance of single-input-multiple-output systems over correlated κ-μ shadowed fading channels is investigated. In particular, based on the classic Wyner's wiretap model, we derive analytical expressions for secure outage ...

On Secrecy Performance of Mixed RF-FSO Systems

open access: yesIEEE Photonics Journal, 2017
In this paper, we study the secrecy performance of a mixed radio frequency-free space optical (RF-FSO) transmission systems. All RF links experience Nakagami-$m$ fading and the FSO link experiences the Gamma–Gamma fading.

Secure communications with cooperative jamming: optimal power allocation and secrecy outage analysis [PDF]

open access: yes, 2017
This paper studies the secrecy rate maximization problem of a secure wireless communication system in the presence of multiple eavesdroppers. The security of the communication link is enhanced through cooperative jamming with the help of multiple jammers.
