Abstract

In this work a theoretical investigation regarding the availability of a Free Space Optical communication system was carried out. The statistical distribution of the photocurrent generated at the receiver by a Gaussian beam after propagating through the random medium was investigated. The photocurrent's relative frequencies were obtained by means of computer simulation and the cases where beam wandering was present were taken into account. An experimental set up was mounted for comparisons purposes. Finally, with the knowledge of the photocurrent statistical distribution, the system availability and the Bit Error Rate were estimated under several system configurations and impairments conditions.
