Buffer-Aided Max-Link Relaying for Free Space Optical Communication With Delay Constraints
IEEE Photonics Journal, 2022 In this paper, we introduce the concept of buffer-aided cooperative relaying for a free-space optical (FSO) communication system. The proposed FSO system consists of $K$ decode-and-forward(DF) relays, each equipped with a buffer of size $L$. The proposed

Optical Orbital Angular Momentum Shift-Keying Communication Using Direct Demodulation
IEEE Access, 2019 Orbital angular momentum (OAM) shift-keying (SK), which manifests as the rapid switching of OAM modes, is crucial but severely hampered for lacking effective demodulation techniques in OAM communication.

Communication protocols for Free-Space Optical links [PDF]
, 2015 Táto diplomová práca sa zaoberá správaním protokolu TCP/IP pri prechode bezdrôtovým optickým spojom, ktorý je ovplyvnený atmosférickými turbulenciami. Tie spôsobujú fluktuáciu prijímaného optického výkonu a tým zmenu bitovej chybovosti spoja.
