    • C-RAN in realistic scenarios 

      Stante, Roberto (Universitat Politècnica de Catalunya, 2019-01-09)
      Master thesis
      Open Access
      Covenantee:   Università degli Studi dell'Aquila
      In the first part is described the LTE system containing a description of all the aspects and parameters that should be taken into account when planning. Then there is a Software Planning Tool named Mentum Planet guidelines ...

    • Hyperparameter configuration of a frequency optimization algorithm for multi-beam satellite constellations 

      Aliaga Torrens, Sergi (Universitat Politècnica de Catalunya, 2021-05-26)
      Bachelor thesis
      Open Access
      Covenantee:   Massachusetts Institute of Technology
      Desenvolupament d'una metodologia per configurar algorismes enfocats al problema de la Gestió Dinàmica de Recursos en Comunicacions per Satèl·lit, usant un algorisme d'Assignació de Freqüències com a cas d'estudi.

    • Joint beam-hopping scheduling and power allocation in NOMA-assisted satellite systems 

      Wang, Anyue; Lei, Lei; Lagunas Targarona, Eva; Chatzinotas, Simeon; Pérez Neira, Ana Isabel; Ottersten, Bjorn (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      In this paper, we investigate potential synergies of non-orthogonal multiple access (NOMA) and beam hopping (BH) for multi-beam satellite systems. The coexistence of BH and NOMA provides time-power-domain flexibilities in ...

    • Maximum likelihood estimation of position in GNSS 

      Closas Gómez, Pau; Fernández Prades, Carlos; Fernández Rubio, Juan Antonio (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-05)
      Article
      Open Access
      In this letter, we obtain the Maximum Likelihood Estimator of position in the framework of Global Navigation Satellite Systems. This theoretical result is the basis of a completely different approach to the positioning ...
