Abstract

Free-Space Optical communications (FSO) propagated over a clear atmosphere suffers from irradiance fluctuation caused by small but random atmospheric temperature fluctuations. This results in decreased Signal-to-Noise Ratio (SNR) and consequently impaired performance. In this paper, the Bit Error Rate (BER) performance of FSO communication systems employing Binary Phase Shift Keying (BPSK) modulation is derived. To evaluate the system error performance in weak turbulence regime, the Probability Density Function (pdf) of the received irradiance after traversing the atmosphere is modeled using the log normal distribution. The effects of pointing errors on the performance of a FSO communication system are studied
