(MDPI, 2023-05-09)Over the last few decades, an increasing economic and social flooding damages trend has been recorded worldwide. Although this situation was initially associated with climate change, recently different institutions and ... -
Are wind turbines integrated into landscape? an analysis of its social perception in a spanish mediterranean area
(Springer, 2023)Context Renewable energy sources development has introduced wind farms as a regular landscape element. However, as human-made elements, wind farms infuence on landscape’s scenic beauty diferently according to the ... -
Inversión aproximada de matrices en sistemas Massive MIMO correlados en tiempo o frecuencia
Cobos Morales, Óscar; Soldado Guerrero, Rafael; Martos-Naya, Eduardo; López Martínez, Francisco Javier; Entrambasaguas-Muñoz, José Tomás (2018-09-20)
Massive multiple-input multiple-output (MIMO) is expected to be one of the keys in 5G. In this technology, the base station is equipped with a big number of antennas serving multiple users simultaneously to improve spectral ... -
On the connection between noncircularly-symmetric and noncentral fading models: univariate and multivariate analysis
Moreno-Pozas, Laureano (UMA Editorial, 2017-06-01)
This thesis provides new statistical connections between noncircularly-symmetric central and circularly-symmetric noncentral underlying complex Gaussian models. This is particularly interesting since it facilitates the ... -
On the effect of random power availability in wireless power transfer systems with physical layer security
In this paper, we evaluate the performance of wireless powered communication systems from a physical layer security perspective. Our aim is to determine under which conditions the random power availability due to wireless ... -
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 ... -
Statistical Characterization of the Chunk Size Distribution in DASH
Vaca-Rubio, Cristian J.; Gómez-Paredes, Gerardo; Aguayo-Torres, María del Carmen; López Martínez, Francisco Javier (2019-09-13)
We present a statistical characterization of the segment size distribution of video streaming services based on dynamic adaptive streaming over HTTP (DASH). We first obtain the empirical distributions from traffic captures ...
