Improved analysis of 2.5 Gbps-inter-satellite link (ISL) in inter-satellite optical-wireless communication (IsOWC) system
Vishal Sharma,Naresh Kumar +1 more
TL;DR: Improved investigation through implementation of a square root module using OPTISYSTEM™ simulator to establish an inter-satellite link (ISL) between two satellites estranged by a distance of 1000 Km at data rate of 2.5 Gbps which is not reported in previous investigated work.
