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…
A New Interweave Cognitive Radio Scheme for Out-band Energy Harvesting Systems
Nikolaos I. Miridakis, Theodoros A. Tsiftsis
In this paper, a new interweave cognitive radio (CR) transmission scheme is analytically presented for energy harvesting (EH)-enabled transmitting nodes. EH is performed via a dedi…
MIMO Underlay Cognitive Radio: Optimized Power Allocation, Effective Number of Transmit Antennas and Harvest-Transmit Tradeoff
Nikolaos I. Miridakis, Theodoros A. Tsiftsis, George C. Alexandropoulos
In this paper, the performance of an underlay multiple-input multiple-output (MIMO) cognitive radio system is analytically studied. In particular, the secondary transmitter operate…
