      Article
      Accés obert
      In this work, we numerically consider a thermoelastic problem where the thermal law is modeled using the so-called Moore-Gibson-Thompson equation. This thermomechanical problem is written as a coupled system composed of a ...

    • Dynamic and efficient point-to-point and point-to-multipoint communications by slicing the optical constellation

      Comunicació de congrés
      Accés obert
      Optical Constellation Slicing is proposed to convey heterogenous traffic from a source to multiple destinations, while supporting dynamic capacity allocation. Illustrative numerical results reveal the potential of the ...

    • Dynamic subcarrier allocation for multipoint-to-point optical connectivity 

      Shakespear Miles, Hailey Josephine; Ruiz Ramírez, Marc; Napoli, Antonio; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Text en actes de congrés
      Accés obert
      A mathematical programming model is proposed to dynamically allocate subcarriers in the upstream direction of point-to-multipoint connections based on Digital Subcarrier Multiplexing. Numerical results show significant ...

    • Efficient margin adaptive scheduling for MIMO-OFDMA systems 

      Moretti, Marco; Pérez Neira, Ana Isabel (2013-01)
      Article
      Accés restringit per política de l'editorial
      In this paper we address the problem of margin adaptive scheduling in the downlink of an orthogonal frequency division multiple access (OFDMA) multiple-input multiple-output (MIMO) system. Optimal resource allocation in ...
