A new Approach to the Statistical Analysis of Non-Central Complex Gaussian Quadratic Forms With Applications
Ramírez Espinosa, Pablo; Moreno-Pozas, Laureano; París-Ángel, José Francisco; Cortés-Arrabal, José Antonio; Martos-Naya, Eduardo (Institute of Electrical and Electronics Engineers, 2019-07)This paper proposes a novel approach to the statistical characterization of non-central complex Gaussian quadratic forms (CGQFs). Its key strategy is the generation of an auxiliary random variable that replaces the original ... -
An Extension of the κ -μ Shadowed Fading Model: Statistical Characterization and Applications.
Ramírez Espinosa, Pablo; López-Martínez, Francisco Javier; París-Ángel, José Francisco; Yacoub, Michel Daoud; Martos-Naya, Eduardo (IEEE, 2017-12-25)We here introduce an extension and natural generalization of both the κ-μ shadowed and the classical Beckmann fading models: the Fluctuating Beckmann (FB) fading model. This new model considers the clustering of multipath ... -
Análisis estadístico de formas cuadráticas gaussianas complejas no centrales
Martos-Naya, Eduardo; Ramírez Espinosa, Pablo; Cortés-Arrabal, José Antonio; París-Ángel, José Francisco (2018-09-13)En este artículo se presenta un nuevo enfoque al análisis estadístico de las formas cuadráticas gaussianas complejas (FCGC) indefinidas y no centrales. Este nuevo enfoque se basa en el estudio de una variable aleatoria ... -
Analysis of Gaussian Quadratic Forms with Application to Statistical Channel Modeling
Ramírez Espinosa, Pablo (UMA Editorial, 2020)En esta tesis se presenta una nueva aproximación a la distribución de de formas cuadráticas gaussianas (FCGs) no centrales tanto en variables reales como complejas. Para ello, se propone un nuevo método de análisis de ... -
Backing off from rayleigh and rice: Achieving perfect secrecy in wireless fading channels
Ramírez Espinosa, Pablo; López-Martínez, Francisco Javier (Escuela Técnica Superior de Ingeniería de Telecomunicación de la UMA, 2020-09)We show that for a legitimate communication under multipath quasi-static fading with a reduced number of scatter- ers, it is possible to achieve perfect secrecy even in the presence of a passive eavesdropper for which no ... -
Composite Fading Models Based on Inverse Gamma Shadowing: Theory and Validation.
Ramírez Espinosa, Pablo; López-Martínez, Francisco Javier (IEEE, 2021-03-17)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 choice for modeling shadow fading, by ... -
On the Utility of the Inverse Gamma Distribution in Modeling Composite Fading Channels
Ramírez Espinosa, Pablo; López-Martínez, Francisco Javier (2020-01-20)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 choice for modeling shadow fading, by means ... -
Physical Layer Security of Large Reflecting Surface Aided Communications with Phase Errors.
Vega-Sánchez, José David; Ramírez Espinosa, Pablo; López-Martínez, Francisco Javier (IEEE, 2020-10-09)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 that express the LRS-based composite channel ... -
The κ - μ shadowed fading model with arbitrary intercluster correlation
Ramírez Espinosa, Pablo; París-Ángel, José Francisco; Cortés-Arrabal, José Antonio; Martos-Naya, Eduardo (2018-09-03)In this paper, we propose a generalization of the well-known κ-μ shadowed fading model. Based on the clustering of multipath waves as the baseline model, the novelty of this new distribution is the addition of an arbitrary ...
