| dc.description.abstract | Free space optical (FSO) communication has emerged as a viable
technology for broadband wireless applications which offers the potential of high
bandwidth capacity over unlicensed optical wavelengths.Atmospheric turbulence
has a significant impact on the quality of a laser beam propagating through the
atmosphere over long distances. For optical wireless communication systems,
most frequently used system is Intensity Modulated Direct Detection (IM/DD)
system. For FSO systems, although the power efficiency is inferior to PPM, OOK
encoding is more commonly used due to its efficient bandwidth usage and
robustness to timing errors. In the presence of atmospheric turbulence, the
received signal exhibits random intensity fluctuations which increase the BER. In
this dissertation the characteristics and properties of several important design
parameters are discussed with the modulation analysis and the link performance
evaluated under considering the effects of the atmospheric turbulence's which is
the great challenges for the FSO. | en_US |
