Adaptive symbol-rate free-space-optical communications [PDF]
2013 Australian Communications Theory Workshop (AusCTW), 2013 Free space optical communications through fading atmospheric channels can achieve improved throughput by using adaptive transmission techniques. This paper considers the use of adaptive symbol-rate and transmit-power methods. We use an idealised model of channel coding that assumes zero errors can be achieved above some SNR threshold and adjust the ...

Fading testbed for free-space optical communications [PDF]
SPIE Proceedings, 2016 Free-space optical (FSO) communication is a very attractive technology offering very high throughput without spectral regulation constraints, yet allowing small antennas (telescopes) and tap-proof communication. However, the transmitted signal has to travel through the atmosphere where it gets influenced by atmospheric turbulence, causing scintillation
