    • Variation of ionospheric narrowband and wideband performance for a 12,760 km transequatorial link and its dependence on solar and ionospheric activity 

      Alsina Pagès, Rosa Maria; Altadill Felip, David; Blanch Llosa, Estefania; Segarra, Antoni; Hervas García, Marcos Antonio; González Sans, Xavier (Multidisciplinary Digital Publishing Institute (MDPI), 2020-09-01)
      Article
      Accés obert
      The ionosphere provides a channel that is able to propagate electromagnetic waves for long-haul communications, allowing Non-Line-Of-Sight (NLOS) radio communications in the high-frequency band (HF). Nonetheless, its ...
