• 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 ...
    • Radio interference analysis tool based on GNU Radio 

      Yébenes Gálvez, José Antonio; Martos-Naya, Eduardo; Aguayo-Torres, Maria del Carmen; Cárdenas-Angelat, Carlos; Baños-Polglase, Juana Daphne (2019-10-30)
      Avoiding interference is one of the main challenges in radio communications. Interference hunting is usually done with costly instruments. In this work, a cost efficient portable tool is described for interference analysis ...
    • The dynamics of user channels in massive MIMO systems 

      Martos-Naya, Eduardo; Lopez-Martinez, F. Javier; Paris-Angel, Jose Francisco; Goldsmith, Andrea (2014-10-31)
      The SNR associated with the different users in large-scale MIMO systems depends on the magnitude of the eigenvalues of the channel power matrix HH H. While it is known that the spread between the best and worst channels ...
    • A Tractable Line-of-Sight Product Channel Model: Application to Wireless Powered Communications 

      Lopez-Martinez, F. Javier; Moreno-Pozas, Laureano; Fernández-Plazaola, Unai; Paris-Angel, Jose Francisco; Martos-Naya, Eduardo; [et al.] (2018-07-30)
      We here 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 random variables. Simple closed-form ...
    • 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 ...
