On Physical Layer Security of Double Rayleigh Fading Channels for Vehicular Communications
Ai, Yun; Cheffena, Michael; Mathur, Aashish; Lei, Hongjiang (Journal article; Peer reviewed, 2018)In this letter, we study the physical layer secrecy performance of the classic Wyner's wiretap model over double Rayleigh fading channels for vehicular communications links. We derive novel and closed-form expressions for ... -
Physical Layer Security of Hybrid Satellite-FSO Cooperative Systems
Ai, Yun; Mathur, Aashish; Cheffena, Michael; Bhatnagar, Manav R.; Lei, Hongjiang (Journal article; Peer reviewed, 2019)In this paper, we study the physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system. The satellite links are assumed to follow the Shadowed-Rician fading distribution; and ... -
Secrecy enhancement of RF backhaul system with parallel FSO communication link
Ai, Yun; Mathur, Aashish; Lei, Hongjiang; Cheffena, Michael; Imran Shafique, Ansari (Peer reviewed; Journal article, 2020)This paper analyses the physical layer secrecy (PLS) performance of a hybrid free space optical and radio frequency (FSO/RF) communication system under a modified selection combining scheme. The transmission scheme takes ...
