Mixed RF-VLC Relaying Systems for Interference-Sensitive Mobile Applications
Milica I. Petkovic, Aleksandra M. Cvetkovic, Milan Narandzic +3
Due to their Radio-Frequency (RF) immunity, Visible Light Communications (VLC) pose as a promising technology for interference sensitive applications such as medical data networks.…
Optimal Primary-Secondary user Cooperation Policies in Cognitive Radio Networks
Nestor Chatzidiamantis, Evangelia Matskani, Leonidas Georgiadis +2
In cognitive radio networks, secondary users (SUs) may cooperate with the primary user (PU), so that the success probability of PU transmissions are improved, while SUs obtain more…
Adaptive Subcarrier PSK Intensity Modulation in Free Space Optical Systems
Nestor D. Chatzidiamantis, Athanasios S. Lioumpas, George K. Karagiannidis +1
We propose an adaptive transmission technique for free space optical (FSO) systems, operating in atmospheric turbulence and employing subcarrier phase shift keying (S-PSK) intensit…
