Extreme Age of Information for Wireless-Powered Communication Systems
Nikolaos I. Miridakis, Zheng Shi, Theodoros A. Tsiftsis +1
The extreme or maximum age of information (AoI) is analytically studied for wireless communication systems. In particular, a wireless powered single-antenna source node and a recei…
Semi-Blind Multiuser Detection Under the Presence of Reconfigurable Intelligent Surfaces
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang +2
A multiuser multiple-input multiple-output wireless communication system is analytically studied, which operates with the aid of a reconfigurable intelligent surface (RIS). The int…
Performance of Uplink NOMA with User Mobility Under Short Packet Transmission
Nikolaos I. Miridakis, Emmanouel T. Michailidis, Angelos Michalas +3
The scenario of an uplink two-user non-orthogonal multiple access (NOMA) communication system is analytically studied when it operates in the short packet transmission regime. The…
Energy Optimization in Massive MIMO UAV-Aided MEC-Enabled Vehicular Networks
Emmanouel T. Michailidis, Nikolaos I. Miridakis, Angelos Michalas +3
This paper presents a novel unmanned aerial vehicle (UAV) aided mobile edge computing (MEC) architecture for vehicular networks. It is considered that the vehicles should complete…
Generalized Energy Detection Under Generalized Noise Channels
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang
Generalized energy detection (GED) is analytically studied when operates under fast-faded channels and in the presence of generalized noise. For the first time, the McLeish distrib…
Moment-based Spectrum Sensing Under Generalized Noise Channels
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Guanghua Yang
A new spectrum sensing detector is proposed and analytically studied, when it operates under generalized noise channels. Particularly, the McLeish distribution is used to model the…
