Measurements of aperture averaging on bit-error-rate [PDF]
SPIE Proceedings, 2005 We report on measurements made at the Shuttle Landing Facility (SLF) runway at Kennedy Space Center of receiver aperture averaging effects on a propagating optical Gaussian beam wave over a propagation path of 1,000 m. A commercially available instrument with both transmit and receive apertures was used to transmit a modulated laser beam operating at ...

Average Bit Error Rate at Signal Transmission with OOK Modulation Scheme in Different FSO Channels
Tehnicki vjesnik - Technical Gazette, 2021 In this paper, the Average Bit Error Rate of the signal in the Free Space Optical system modulated with On-Off keying scheme is calculated and analysed. The Average Bit Error Rate is determined in the case of an atmospheric channel modelled with Gamma-Gamma distribution, Log-Normal distribution, K distribution and I-K distribution.
