    • Rate optimization for RIS-aided mMTC networks in the finite blocklength regime 

      Liesegang Maria, Sergi; Zappone, Alessio; Muñoz Medina, Olga; Pascual Iserte, Antonio (2023-03)
      Article
      Accés obert
      Reconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In the context of massive machine-type communications (mMTC), a RIS can be used to support the ...

      Article
      Accés obert
      In this paper, we address the design of multi-user multiple-input single-output (MU-MISO) precoders for indoor visible light communication (VLC) systems. The goal is to minimize the transmitted optical power per light ...

    • Sensor selection and distributed quantization for energy efficiency in massive MTC

      Article
      Accés obert
      This paper presents an estimation approach within the framework of uplink massive machine-type-communications (mMTC) that considers the energy limitations of the devices. We focus on a scenario where a group of sensors ...

    • Small rural operators techno-economic analysis to bring mobile services to isolated communities: The case of Peru Amazon rainforest

      Article
      Accés obert
      A large number of rural communities in developing countries do not have access to communications services, unlike urban areas where these services have rapidly grown. This connectivity gap is mainly caused by the urban-oriented ...

    • Spatial-temporal processing with restriction of degrees of freedom for CDMA-multiuser detection 

      Muñoz Medina, Olga; Fernández Rubio, Juan Antonio (1998)
      Text en actes de congrés
      Accés obert
      Multipath distortion and multiple access interference are major limitations for the performance of wireless CDMA systems. In order to overcome both problems, a base-station antenna array RAKE receiver is proposed in this ...

    • Stochastic geometry analysis and design of wireless powered MTC networks 

      Liesegang Maria, Sergi; Muñoz Medina, Olga; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés obert
      Machine-type-communications (MTC) are being crucial in the development of next generation mobile networks. Given that MTC devices are usually battery constrained, wireless power transfer (WPT) and energy harvesting (EH) ...

    • Stochastic resource allocation with a backhaul constraint for the uplink 

      Rubio López, Javier; Muñoz Medina, Olga; Pascual Iserte, Antonio; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés obert
      We propose a novel stochastic radio resource alloca- tion strategy for the uplink that achieves long-term fairness in terms of similar bitrates considering backhaul and air-interface capacity limitations. We focus on a ...

    • The DoF of the 3-User (p, p+1) MIMO Interference Channel 

      Torrellas Socastro, Marc; Agustín de Dios, Adrián; Vidal Manzano, José; Muñoz Medina, Olga (2014-11-01)
      Article
      Accés restringit per política de l'editorial
      The degrees of freedom (DoF) of the 3-user multiple-input multiple-output (MIMO) interference channel (IC) with full channel state information and constant channel coefficients are investigated when (p, p + 1) antennas are ...
