摘要：Over recent last decades free space optical communication (FSO) has become more interesting and itcan be seen as an alternative to radio frequency communication. FSO is a very long technology to fix the opticalradiation that pass through the atmosphere from one point to other. Atmospheric turbulence induced fading is one ofthe main disadvantage that affects the Free Space Optical communication. Relay assisted Free Space Opticalcommunication employing ON-OFF Keying (OOK) is employed as modulation technique. FSO communication is donein LDPC coding and convolutional coding are being analysed. The performance results are evaluated in terms of biterror rate (BER). It is found that relay assisted LDPC coded Free Space Optical system with OOK modulationtechnique provides higher performance.
