Análisis estadístico de formas cuadráticas gaussianas complejas no centrales
Martos-Naya, Eduardo
; Ramírez Espinosa, Pablo; Cortes-Arrabal, Jose Antonio; Paris-Angel, Jose 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
(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
(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 ... -
On the Utility of the Inverse Gamma Distribution in Modeling Composite Fading Channels
(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 ... -
The κ - μ shadowed fading model with arbitrary intercluster correlation
Ramírez Espinosa, Pablo; Paris-Angel, Jose Francisco; Cortes-Arrabal, Jose 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 ...
