A MATLAB program for the computation of the confluent hypergeometric function Φ2
Martos-Naya, Eduardo; Romero-Jerez, Juan Manuel; López-Martínez, Francisco Javier; París-Ángel, José Francisco (2016-09-22)We here present a sample MATLAB program for the numerical evaluation of the confluent hypergeometric function Φ2. This program is based on the calculation of the inverse Laplace transform using the algorithm suggested by ... -
A Tractable Product Channel Model for Line-of-Sight Scenarios.
Fernández-Plazaola, Unai; Moreno-Pozas, Laureano; López-Martínez, Francisco Javier; París-Ángel, José Francisco; Martos-Naya, Eduardo; Romero-Jerez, Juan Manuel[et al.] (IEEE, 2020-01-06)We present a general and tractable fading model for line-of-sight (LOS) scenarios, which is based on the product of two independent and non-identically distributed κ-μ shadowed power envelopes. Simple closed-form expressions ... -
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

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 Some Unifications Arising from the MIMO Rician Shadowed Model
Moreno-Pozas, Laureano; Martos-Naya, Eduardo (IEEE, 2016)This paper shows that the proposed Rician shadowed model for multi-antenna communications allows for the unification of a wide set of models, both for multiple-input multiple-output (MIMO) and single- input single-output ... -
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 ... -
Optimización de técnicas de sincronización en sistemas de transmisión multiportadora
Martos-Naya, Eduardo (Universidad de Málaga,, 2005)El objetivo de esta tesis es la optimización o mejora de técnicas de sincronización en sistemas DMT, aunque se ha centrado fundamentalmente en el análisis y diseño optimizado de los sitemas de corrección digital del ... -
