    • Novel radio environment map for the ns-3 NR simulator 

      Koutlia, Katerina; Bojovic, Biljana; Lagén Morancho, Sandra; Giupponi, Lorenza (Association for Computing Machinery (ACM), 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Radio Environmental Map (REM) is a useful tool to visualize the network coverage, including signal quality and interference, in multi-cell scenarios. Although REM maps for omnidirectional transmissions/receptions and tools ...

    • On the superiority of improper Gaussian signaling in wireless interference MIMO scenarios 

      Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (2016-08)
      Article
      Accés obert
      Recent results have elucidated the benefits of using improper Gaussian signaling (IGS) as compared to conventional proper Gaussian signaling (PGS) in terms of achievable rate for interference-limited conditions. This paper ...

    • Performance analysis of feedback-free collision resolution NDMA protocol 

      Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José; García Mateos, Jorge (2018-12-01)
      Article
      Accés obert
      To support communications of a large number of deployed devices while guaranteeing limited signaling load, low energy consumption, and high reliability, future cellular systems require efficient random access protocols. ...

    • Realistic beamforming design using SRS-based channel estimate for ns-3 5G-LENA module 

      Bojovic, Biljana; Lagén Morancho, Sandra; Giupponi, Lorenza (Association for Computing Machinery (ACM), 2021)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Beamforming (BF) is a key procedure to overcome propagation limits in millimeter-wave bands but also to extend network coverage in sub 6 GHz bands, as considered in recent 3GPP and IEEE communication standards. Up to date, ...

    • Signal-timing offset compensation in dense TDD OFDM-based networks 

      Agustín de Dios, Adrián; Lagén Morancho, Sandra; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés obert
      Orthogonal Frequency Division Multiplexing (OFDM)-based networks rely on time synchronization to obtain their best performance. Time synchronization with neighboring nodes can be satisfied by increasing the cyclic prefix ...
