Simulation of atmospheric optical channel with ISI

The paper deals with the simulation of transmission properties of atmospheric optical channel and with the analysis of receiver with equalizer for terrestrial Free-Space Optical links. During clear weather condition the optical channel is almost band-unlimited. Multipath propagation during fog events decreases the channel bandwidth, which results in intersymbol interference. Based on the Monte-Carlo simulations the application of a simple zero-forcing equalizer is evaluated. Key-Words: Free-space optical links, Atmospheric scattering, ISI, Equalizer
