Physical Layer Security of Large Reflecting Surface Aided Communications with Phase Errors
Jose David Vega Sanchez, Pablo Ramirez-Espinosa, F. Javier Lopez-Martinez
The physical layer security (PLS) performance of a wireless communication link through a large reflecting surface (LRS) with phase errors is analyzed. Leveraging recent results tha…
Effect of Correlation between Information and Energy Links in Secure Wireless Powered Communications
Antonio Tarrías-Muñoz, José Luis Matez-Bandera, Pablo Ramírez-Espinosa +1
In this paper, we investigate the impact of correlation between the energy and information links in wireless power transfer systems, from a physical layer security perspective. Wit…
On the Effect of Correlation on the Capacity of Backscatter Communication Systems
J. L. Matez-Bandera, P. Ramirez-Espinosa, J. D. Vega-Sanchez +1
We analyse the effect of correlation between the forward and backward links on the capacity of backscatter communication systems. To that aim, we obtain an analytical expression fo…
On the Beneficial Role of a Finite Number of Scatterers for Wireless Physical Layer Security
Pablo Ramírez-Espinosa, R. José Sánchez-Alarcón, F. Javier López-Martínez
We show that for a legitimate communication under multipath quasi-static fading with a reduced number of scatterers, it is possible to achieve perfect secrecy even in the presence…
Composite Fading Models based on Inverse Gamma Shadowing: Theory and Validation
Pablo Ramírez-Espinosa, F. Javier Lopez-Martinez
We introduce a general approach to characterize composite fading models based on inverse gamma (IG) shadowing. We first determine to what extent the IG distribution is an adequate…
The α-κ-μ Shadowed Fading Distribution: Statistical Characterization and Applications
Pablo Ramirez-Espinosa, Jules M. Moualeu, Daniel Benevides da Costa +1
We introduce the α-κ-μ shadowed (α-KMS) fading distribution as a natural generalization of the versatile α-κ-μ and α-η-μ distributions. The α-KMS fading distribution unifies a wide…
An Extension of the κ-μShadowed Fading Model: Statistical Characterization and Applications
Pablo Ramirez-Espinosa, F. Javier Lopez-Martinez, Jose F. Paris +2
We here introduce an extension and natural generalization of both the κ-μshadowed and the classical Beckmann fading models: the Fluctuating Beckmann (FB) fading model. This new…
