Performance Analysis of Inter-Satellite Optical Wireless Communication (Is-OWC) System by Using Channel Diversity Technique

In modern era optical wireless communication is the fast, cost effective, high end security and convenient technique. Is-OWC is the technology used to communicate one satellite to another, whether the satellite revolve in same orbit or in the different orbit. In this paper, we used channel diversity technique which gives better result compared to single channel. Diversity technique in Is-OWC system provide multiple path to signal which help to increase the Q-factor and signal strength at large distance. Here, we have analyzed the designing and simulation of Is-OWC system by using OPTISYSTEM 7.0 software. The system is used multiple OWC channels at 40 Gbps data rate with distance range of 5000 km and pointing error of $1.1\ {\mu} \mathbf{rad}$ and result shown in the form of BER, quality factor and eye diagram.
