Free Space Optical (FSO) Communications are able to deliver us to an age of unprecedented bandwidth, low signal attenuation, small space requirements and ultimately low cost. In FSO communications the influence of atmospheric effects can be specified by the attenuation and fluctuations of the transmitted optical power, caused by the atmospheric turbulence. This paper investigate the performance of FSO communication systems employing on-off keying (OOK) , subcarrier binary phase-shift keying (BPSK) modulation and Q-ary pulse position modulation (QPPM) in turbulence regime. The performance resul...
