Design And Analysis of Transceiver Using Co-Operative Diversity to Reduce Fading Over FSO Links
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 3
Abstract
In this paper, To combat against the atmospheric turbulence induced fading over FSO link a spatial diversity technique is used to design the transceiver. Cooperative diversity is proposed and analyzed in noncoherent FSO communications with intensity modulation and direct detection (IM/DD). The error performance is derived in semi analytical and closed form expressions in the presence and absence of background radiation respectively. Performance analysis is carried out in the four strategies over both Rayleigh and lognormal fading models. This analysis may recommend the usage of the FSO links in the higher layers. After depth analysis, a technique is adopted from the possible solutions to mitigate building sway and atmospheric effects at the network layer.
