• Evaluating noise in passive beam forming networks for multibeam applications 

      Biurrun Quel, Carlos Upna Orcid; Río Bocio, Carlos del Upna Orcid (Elsevier, 2023)   Artículo / Artikulua  OpenAccess
      In this work, we identify that the analysis in terms of noise of multibeam passive beam forming networks requires a proper formulation, in order not to overestimate the noise generated by the network. We show that the ...
    • Hybrid computational techniques: electromagnetic propagation analysis in complex indoor environments 

      Azpilicueta Fernández de las Heras, Leyre Upna Orcid; Falcone Lanas, Francisco Javier Upna Orcid; Janaswamy, Ramakrishna (IEEE, 2019)   Artículo / Artikulua  OpenAccess
      In this article, we compare deterministic methodologies for characterizing channel behavior in heterogeneous and composite scenarios. These techniques include one that combines a 3D ray launching (RL) approach based on ...
    • A radio channel model for D2D communications blocked by single trees in forest environments 

      Picallo Guembe, Imanol Upna Orcid; Klaina, Hicham Upna; López Iturri, Peio Upna Orcid; Aguirre Gallego, Erik Upna Orcid; Celaya Echarri, Mikel Upna Orcid; Azpilicueta Fernández de las Heras, Leyre Upna Orcid; Eguizábal Garrido, Alejandro; Falcone Lanas, Francisco Javier Upna Orcid; Alejos, Ana (MDPI, 2019)   Artículo / Artikulua  OpenAccess
      In this paper we consider the D2D (Device-to-Device) communication taking place between Wireless Sensor Networks (WSN) elements operating in vegetation environments in order to achieve the radio channel characterization ...
