Performance Analysis and Optimization with Varied Parameters for InterSatellite Optical Wireless Communication System

Abstract

The day to day evolution has advanced the optical communication system from lengthy fibers to wireless
system. This can be concluded as the optical systems have resulted to be used in space as a medium to communicate
between two satellites. Optical wireless communication provides a very important method for the satellites orbiting
around the earth to communication with each other such as inter-satellite transmission system. For exchanging data
from different states, country numbers of satellite are increasing day by day. So, for inter-satellite communication we
are using optical wireless communication to exchange the data while depending upon the parameters like Bit error
rate, Q-factor and the received power. In IsOWC link two parameters mainly distance and aperture diameter is
adjusted. In this optical inter-satellite link is modeled where the effect of distance, bit rate and input power are varying
with aperture diameter of the transmitter and the receiver telescope is analyzed. And we are also optimizing the results
with varied parameters like aperture diameter of the transmitter and receiver, bit rate, input power and the received
power. The inter-satellite links were modeled and simulated with the help of optical system simulator named
OPTISYSTEM software.
