Abstract: Free Space Optical (FSO) communications has regained a great interest over the last few year, where optical transmission line uses the optical fibers cables as medium but in free space optical link we us the space as the medium to transmit the optical signal. The transmission medium of free space optical is significantly affected by the various weather conditions such as rain, fog, snow, wind, etc.
The performance of FSO system has faced adverse consequences due to various changes in the properties of the channel such as weather conditions and length of the channel up to which the information needs to be transmitted. This paper, study quality factor (Q-factor) for using two types of modulation formats and compares their performance. Hence the performance was analyzed by the Q-factor with respect to varying distance, data rate.
Keywords: Free Space RZ and NRZ technique, Q-factor, optical communications
