Original Abstract

The paper deals with a parameterized model for simulation of packet transmission on atmospheric Free-Space Optical (FSO) links. Due to the effect of atmospheric turbulence the channel is characterized by signal fluctuations in the order of tens of milliseconds. For moderate transmission rates the FSO channel can be simply modeled as a channel with slowly varying random attenuation, which is generated by the proposed model by means of low-pass filtering a random number sequence. The probability of occurrence of errors in each packet can be computed using analytical formulae based on the generated signal level and noise performance of the receiver. The model shows a good agreement with measured data. It has been implemented into the OMNeT++ simulator.
