    This paper evaluates different analog-digital beam-forming solutions for future spectrum sharing mm-wave scenarios. In contrast to sub-6 GHz multiantenna schemes where all-digital solutions provide an excellent performance-cost ...
  • Shared access satellite-terrestrial reconfigurable backhaul network enabled by smart antennas at mm-wave band 

    Artiga Campos, Xavier; Pérez Neira, Ana Isabel; Baranda, Jorge; Lagunas Targarona, Eva; Chatzinotas, Symeon; Ziaragkas, Georgios (2018-09-01)
    Article
    Open Access
    5G traffic expectations require not only the appropriate access infrastructure, but also the corresponding backhaul infrastructure to ensure a well-balanced network scaling. Optical fibre and terrestrial wireless backhaul ...
  • Terrestrial-satellite integration in dynamic 5G backhaul networks 

    Artiga Campos, Xavier; Núñez Martínez, José; Pérez Neira, Ana Isabel; Lendrino Vela, Gorka Juan; Fare García, Juan Mario; Ziaragkas, Georgios (2016)
    Conference report
