    • An autoencoder-based solution for IQ constellation analysis 

      Ruiz Ramírez, Marc; Morales López, Javier; Sequeira, Diogo Gonçalo; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      A method for IQ constellation analysis based on Autoencoders is proposed. Exhaustive numerical results show accurate physical metric prediction and large data compression, while providing useful model explainability.
    • Autonomous and energy efficient lightpath operation based on digital subcarrier multiplexing 

      Velasco Esteban, Luis Domingo; Barzegar, Sima; Sequeira, Diogo Gonçalo; Ferrari, Alessio; Costa, Nelson; Curri, Vittorio; Pedro, João; Napoli, Antonio; Ruiz Ramírez, Marc (2021-09)
      Article
      Open Access
      The massive deployment of 5G and beyond will require high capacity and low latency connectivity services, so network operators will have either to overprovision capacity in their transport networks or to upgrade the optical ...
    • Deep learning-based real-time analysis of lightpath optical constellations [Invited] 

      Ruiz Ramírez, Marc; Sequeira, Diogo Gonçalo; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2022-06-01)
      Article

      Optical network automation requires accurate physical layer models, not only for provisioning but also for real-time analysis. In particular, In-Phase (I) and Quadrature (Q) constellation analysis enables deep understanding ...
    • Lightweight optical constellation modeling by concatenating artificial neural networks 

      Sequeira, Diogo Gonçalo; Ruiz Ramírez, Marc; Costa, Nelson; Napoli, Antonio; Pedro, João; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      A lightweight optical constellations modeling method based on concatenating ANNs is proposed. Statistical validation of the reproduced constellations is shown. The method accelerates data generation and facilitates detecting ...
