Free space optics through adverse weather (sponsored
by NSF)
Back to Research Main
Summary
This project investigates
the Free Space Optics (FSO) communication through adverse weather such
as rain, fog, smog, snow. These weather events create attenuation and
scattering which severely degrade communication link performance. The
communication channel is characterized by impulse response based on the
solution of the vector radiative transfer equation. We investigate a
technique to obtain the appropriate transmission rate for specified fog
conditions and also a technique to adjust a receiver’s field of view (FOV)
to study the possibility of improving the link performance.
