Performance Analysis of FSO Communication System: Effects of Fog, Rain and Humidity
Free Space Optics (FSO) is one of the most
promising new access technologies. FSO provides the
transmission of data with unlimited bandwidth. The atmospheric
attenuation is caused by two main factors absorption and
scattering. This paper investigates a performance study of free
space optics channel for variable wavelengths 850 nm, 950 nm
and 1550 nm at distance range of 1 km. The simulation reports
minimum BER for NRZ-OOK modulation technique at different
receiver diameters in presence of fog, rain and humidity
attenuation. The obtained results reflect the system improvement
achieving minimum BER and maximum received power that can
be detected at distance 1 km. |
