Performance of BPSK subcarrier intensity modulation free-space optical communications using a log-normal atmospheric turbulence model [PDF]
, 2010 In this paper, we present simulation results for the bit error rate (BER) performance and the fading penalty of a BPSK - subcarrier intensity modulation (BPSK-SIM) free-space optical (FSO) communication link in a log-normal atmospheric turbulence model ...

BPSK subcarrier intensity modulated free-space optical communications in atmospheric turbulence [PDF]
, 2009 Free-space optical communications (FSO) propagated over a clear atmosphere suffers from irradiance fluctuation caused by small but random atmospheric temperature fluctuations.

Turbulence Intensity Modulation by Micropolar Fluids
Fluids, 2021 Fluid microstructure nature has a direct effect on turbulence enhancement or attenuation. Certain classes of fluids, such as polymers, tend to reduce turbulence intensity, while others, like dense suspensions, present the opposite results.

Experimental verification of the limits of optical channel intensity reciprocity [PDF]
, 2012 Optical data links through the atmosphere suffer from turbulence-induced signal scintillation. In a coaxially-symmetric bidirectional link scenario, the variations of the axial intensities at both ends are correlated.

Atmospheric Turbulence Effects on Wind-Turbine Wakes: An LES Study
Energies, 2012 A numerical study of atmospheric turbulence effects on wind-turbine wakes is presented. Large-eddy simulations of neutrally-stratified atmospheric boundary layer flows through stand-alone wind turbines were performed over homogeneous flat surfaces with ...

Experimental investigation of the performance of different modulation techniques under controlled FSO turbulence channel [PDF]
, 2010 This paper experimentally investigates and compares the performance of the free space optics system employing three different modulation schemes, on-off keying (OOK) with nonreturn- to-zero (NRZ) and return-to-zero (RZ) and the binary phase shift keying (
