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...
متن کاملFree Space Optical Communication: Challenges and Mitigation Techniques
In recent years, free space optical (FSO) communication has gained significant importance owing to its unique features: large bandwidth, license free spectrum, high data rate, easy and quick deployability, less power and low mass requirement. FSO communication uses optical carrier in the near infrared (IR) and visible band to establish either terrestrial links within the Earth’s atmosphere or i...
متن کاملImpact of atmospheric turbulence on free space optical (FSO) communication
In free-space optical communication links, atmospheric turbulence causes fluctuations in both the intensity and the phase of the received light signal, impairing link performance. Free Space Optical (FSO) communications is the only viable solution for creating a three-dimensional global communications grid of interconnected ground and airborne nodes. The huge amount of data exchange between sat...
متن کاملFree Space Optical Communication : A Review Neha
Complementing wireless radio networks with free-space optics (FSO) achieve high data rates by modulating radio subcarriers over an optical carrier without expensive optical fiber cabling, enabling a pervasive platform for reaching underserved areas. In this paper, we review the main features of Free Space Optical Communication. Keywords— Free space Optics, NRZ, RZ, PIN, APD etc.
متن کاملPerformance Analysis of Data Transmission in Free Space Optical (FSO) Communication
Free space optical (FSO) communication has become a viable technology for a broadband wireless application which offers the potential of high bandwidth capacity over unlicensed optical wavelength. Atmospheric turbulence has most significant impact on the quality of laser beam propagating through the atmosphere over a long distance. For optical wireless communication system, most frequently used...
