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.

A SURVEY ON KEY-AGGREGATE SEARCHABLE ENCRYPTION FOR GROUP DATA SHARING IN CLOUD STORAGE
Security concerns over inadvertent data leaks in the cloud may greatly ease the capability of selectively sharing encrypted data with different users via public cloud storage. So designing such an encryption schem...
Cylindrically Symmetric Bulk Viscous Fluid in Bimetric Relativity
In this paper, cylindrically symmetric space-time is studied with bulk viscous fluid in the context of Rosen’s Bimetric Theory of Relativity. Here it is shown that only vacuum model can be constructed.
Performance of Capacitor Supported SRF based DSTATCOM in Three-Phase Four-Wire Distribution System under Linear and Non-Linear Load Condition
