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...
متن کاملIncremental 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...
متن کاملA Review on Performance Improvement Techniques in Wireless Optical Communication
Optical Wireless Communication (OWC) otherwise known as Free Space Optical (FSO) communication is a future ready wireless technology which solves many communication bottlenecks at very low implementation cost. The performance of FSO is sensitive towards the atmospheric turbulence. By using a proper error correction code this effect can be mitigated. This paper deals with the basic concept of FS...
متن کاملReview of Free-Space Optical Communications Links
Increased needs for bandwidth require technology that goes beyond traditional copper lines. As internet traffic scales faster than Moore’s law, which is the exponential growth in technology, and digging to install lines in metropolitan areas becomes infeasible, the industry has realized the benefits of free-space optical communication. Free-space optical (FSO) communication links are attractive...
متن کاملImpacts of the Negative-exponential and the K-distribution modeled FSO turbulent links on the theoretical and simulated performance of the distributed diffusion networks
Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...
