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…
Evaluation of HTTP/DASH Adaptation Algorithms on Vehicular Networks
Dimitrios J. Vergados, Angelos Michalas, Katina Kralevska +1
Video streaming currently accounts for the majority of Internet traffic. One factor that enables video streaming is HTTP Adaptive Streaming (HAS), that allows the users to stream v…
All-Optical FSO Relaying Under Mixture-Gamma Fading Channels and Pointing Errors
Nikolaos I. Miridakis, Dimitrios D. Vergados, Angelos Michalas
The performance of all-optical dual-hop relayed free-space optical communication systems is analytically studied and evaluated. We consider the case when the total received signal…
All Cognitive MIMO: A New Multiuser Detection Approach with Different Priorities
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, Dimitrios D. Vergados +1
A new detection scheme for multiuser multiple-input multiple-output (MIMO) systems is analytically presented. In particular, the transmitting users are being categorized in two dis…
