Abstract

In this paper, the performance of an FSO wireless communications system is theoretically analyzed, using NRZ, RZ-OOK modulation formats and a Si PIN photodiodes receiver over fog weather conditions. Based on different fog models for optical beam propagation horizontally at 850 nm1550nm on an FSO, the visibility of weather and power of the transmitter under fog weather are analyzed. The characteristics of bit error rate BER for NRZ and RZ-OOK optical modulation formats are studied under different fog models. Simulation results indicate that the performance of 1550nmis more suited for an FSO communication system. On the other hand, we discuss the suitability of fog models under these modulation formats.
