Optical Inter-Orbit Communication Technology:Future Space Communication Infrastructure

Incremental adaptive networks implemented by free space optical (FSO) communication

The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...

Advanced Optical Developments for inter-Satellite Communication

Lower cost: The cost of disposing FSO is lower than that of an RF with comparable data rate. There are no cables to deploy, no expensive rooftop installations required. Based on a recent finding done by an FSO company based in Canada 'fSONA', the cost per Mbps per month based on FSO is about half that of RF based systems [1]. Huge modulation bandwidth: Generally Optical carrier wavelength which...

Modeling of RF Waves in Free Space Optical Communication System Under Gamma-Gamma Turbulent Channel Effect

In this paper, an enhancement design of communication system using optical radio frequency (RF) waves in free space optical communication (FSO) system is presented. To our knowledge, it is the first time that the effect of Gamma-Gamma turbulent channel model on the performance of the proposed system is analyzed and simulated. To obtain an optical communication system with good performance and h...

Cooperative Communication in Free Space Optical Systems

We have investigated the performance improvement of cooperative free space optical (FSO) communication over single input single output (SISO) system in this paper. Bit error rate (BER) analysis for gammagamma channel model with additive white Gaussian noise (AWGN) has been demonstrated for SISO and cooperative system as well where the performance improvement with different combining techniques ...
