      System-Level Analysis for Full-Duplex MmWave Cellular Networks 

      Skouroumounis, Christodoulos; Psomas, Constantinos; Krikidis, Ioannis (2018)
      In this paper, we investigate the performance of full-duplex (FD) radio in large-scale heterogeneous millimeter-wave (mmWave) cellular networks. The FD radio can potentially double the spectral efficiency but its performance ...

      Tone-Index Multisine Modulation for SWIPT 

      Krikidis, Ioannis; Psomas, Constantinos (2019)
      We propose a new simultaneous wireless information and power transfer technique that embeds information bits in the tone index of multisine waveforms. By varying the number of subcarriers of the transmitted bandwidth-constrained ...

      Wireless Power Transfer 

      Psomas, Constantinos; Krikidis, Ioannis (John Wiley & Sons, Ltd, 2018)
      Large-scale wireless networks are characterized by the existence of multi-user interference due to the concurrent transmission of the network's terminals. In networks where the main focus is wireless power transfer (WPT), ...

      A Wireless Powered Feedback Protocol for Opportunistic Beamforming Using Rectenna Arrays 

      Psomas, Constantinos; Krikidis, Ioannis (2018)
      This paper proposes an opportunistic beamforming (OBF) protocol with limited feedback in the context of wireless powered communication networks. The terminals are randomly deployed around an access point (AP) and are ...
