      Text en actes de congrés
      Accés obert
      Receive spatial modulation (RSM) has been proposed as an effective transmission technology for next-generation wireless communications systems because of its reduced complexity and low energy consumption at the receiver ...

    • Low-cost all-optical switching nodes for ultra-dense optical metro-access networks 

      Sarmiento Hernández, Samael; Lázaro Villa, José Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Text en actes de congrés
      Accés obert
      Optical metro-access networks (OMANs) must enable the connectivity among 5G-based radio stations, edge datacentres, businesses, and home users. In such a heterogenous scenario, greater scalability, higher levels of dynamic ...

    • Fengyun-2F/VISSR land surface temperature anomalies between 2014 and 2022 and their potential correlation with earthquakes
