• Calidad de transmisión de vídeo en redes de comunicaciones submarinas 

      Poncela, Javier; Moreno, Jose Miguel (2015-11-24)
      La adquisición de imágenes submarinas plantea en la actualidad importantes dificultades especialmente en términos de coste y/o retardo en la disponibilidad de la información. Las transmisiones de vídeo a través de redes ...
    • Design and characterization of a pure phase modulator based on TNLC 

      Pérez Aguilar, Lorena; Puerta-Notario, Antonio; Garrido-Balsells, José María; del Castillo Vázquez, Miguel (2019-10-22)
      In this work, we present a complete process to obtain a pure phase modulator based on a twisted nematic liquid crystal display (TNLCD). We first describe a simple technique for measuring the physical parameters of each ...
    • 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 ...
    • Subwavelength metamaterial engineering for silicon photonics 

      Halir, Robert; Ortega-Moñux, Alejandro; Soler-Penades, Jordi; Luque-González, Jose Manuel; Sarmiento-Merenguel, Darío; [et al.] (2017-02-06)
      Waveguides structured at the subwavelength scale frustrate di raction and behave as optical metamaterials with controllable refractive index. These structures have found widespread applications in silicon photonics, ranging ...
    • Throughput-based quality adaptation for DASH in 5G mobile networks 

      Aguilar-Armijo, Jesús; Vaca-Rubio, Cristian J.; Gomez-Paredes, Gerardo; Aguayo-Torres, Maria del Carmen; Entrambasaguas-Muñoz, José Tomás (2019-07-24)
      Video streaming in mobile networks is currently the most widely used service and its usage is expected to grow exponentially in the next years. Due to the changing conditions of the radio interface, techniques likes Dynamic ...
    • 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 ...
