  • Channel estimation and hybrid combining for wideband terahertz massive MIMO systems
    Dovelos, Konstantinos; Matthaiou, Michail; Ngo, Hien Quoc; Bellalta, Boris (Institute of Electrical and Electronics Engineers (IEEE), 2021)
    Terahertz (THz) communication is widely considered as a key enabler for future 6G wireless systems. However, THz links are subject to high propagation losses and inter-symbol interference due to the frequency selectivity ...
  • Terahertz communications: Physical layer enablers and analysis
    Dovelos, Konstantinos (Universitat Pompeu Fabra, 2021-11-05)
    Undoubtedly, spectrum scarcity constitutes the main bottleneck of current wireless networks. It is therefore imperative to move beyond the sub-6 GHz band in order to overcome this limitation. Toward this direction, terahertz ...
