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…
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…
Cooperative Relaying in Underlay Cognitive Systems with Hardware Impairments
Nikolaos I. Miridakis, Dimitrios D. Vergados, Angelos Michalas
The performance of an underlay cognitive (secondary) dual-hop relaying system with multiple antennas and hardware impairments at each transceiver is investigated. In particular, th…
Performance Analysis of the Ordered V-BLAST Approach over Nakagami-m Fading Channels
Nikolaos I. Miridakis, Dimitrios D. Vergados
The performance of the V-BLAST approach, which utilizes successive interference cancellation (SIC) with optimal ordering, over independent Nakagami-m fading channels is studied. Sy…
A Receiver-Centric OFCDM Approach with Subcarrier Grouping
Nikolaos I. Miridakis, Dimitrios D. Vergados, Emmanouil Papadakis
In this letter, following a cross-layer design concept, we propose a novel subcarrier grouping technique for Orthogonal Frequency and Code Division Multiplexing (OFCDM) multiuser s…
