In our research, we exploit several wireless optical links in the CTU campus connected into a simple network and as well our dedicated turbulent chamber and OWC laboratory. We characterize atmospheric parameters and from that develop behavioural models of atmospheric turbulence. The error performance of the FSO links under turbulences can be significantly improved using diversity techniques, e.g. by employing multiple transmit or receive apertures or by utilization of several relay FSO links (here, we experimentally test both amplify and forward and regeneration and forward techniques).
Our international collaborators include academic research groups from Northumbria University, KU Leuven, Indian Institute of Technology Delhi and other teams.
