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), ...

Wireless Powered Cognitive Communications with Asynchronous Channel Access
Demarchou, Eleni; Psomas, Constantinos; Krikidis, Ioannis (2019)Future machine type networks, such as the Internet of Things (IoT), will be characterized by sporadic transmissions of short packets. In this paper, we study an asynchronous channel access model performed by a primary ad ...

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 ...
