      Demand for always available high-rate mobile data services is growing rapidly. This puts stress on mobile networks which have to be able to handle increasing mobile traffic demand. MIMO is used in the latest radio communication ...
    • Phase only transmit beamforming for spectrum sharing microwave systems 

      Vázquez, Miguel Ángel; Blanco, Luis; Pérez Neira, Ana Isabel; Lagunas Hernandez, Miguel A. (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      This paper deals with the problem of phase-only transmit beamforming in spectrum sharing microwave systems. In contrast to sub-6 GHz schemes, general microwave systems require a large number of antennas due to its huge ...

    • Signal and noise power spectra in superregenerative oscillators 

      Bonet Dalmau, Jordi; Palà Schönwälder, Pere; Moncunill Geniz, Francesc Xavier; Águila López, Francisco del; Giralt Mas, Ma. Rosa (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Open Access
      This paper presents a method to quantify noise in superregenerative oscillators. A frequency domain technique, originally intended to determine the signal response, can also be used to determine the noise response. This ...

      Fatjó Brugueras, Arnau (Universitat Politècnica de Catalunya, 2008-06-10)
      Master thesis (pre-Bologna period)
      Open Access
      L’objectiu del present document és descriure la funcionalitat del sistema de test d’un receptor de radiodifusió. Aquest receptor té la mida estàndard dels interruptors de paret i és fabricat per a Hotels i empreses ...
    • Space-dimension models of spectrum usage for cognitive radio networks 

      López Benítez, Miguel; Casadevall Palacio, Fernando José (2017-01-01)
      Article
      Open Access
      The dynamic spectrum access (DSA) principle, relying on the cognitive radio (CR) paradigm, allows users to access spectrum over time intervals or spatial areas where it remains unused. Due to the opportunistic nature of ...
