• Analysis of Gaussian Quadratic Forms with Application to Statistical Channel Modeling 

      Ramirez 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, F. 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 ...
    • The κ - μ shadowed fading model with arbitrary intercluster correlation 

      Ramirez Espinosa, Pablo; Paris-Angel, Jose 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 ...
