Performance evaluation of a multiple optical link FSO–FSO
Journal of Optical Communications, 2020Abstract Free-space optics (FSO) connects two distant points by a simple light beam. Currently, this technique is a complement to radio frequency systems and those based on optical fibers. However, its large-scale deployment is slowing down due to major drawbacks such as the short operating distance and its great vulnerability to ...

UAV-Aided Cooperation for FSO Communication Systems [PDF]
IEEE Communications Magazine, 2018 Relay-assisted FSO systems were proposed as a means for remedying the effects of the various atmospheric impairments on the quality of the FSO signal. Conventional relay-assisted FSO systems, however, are designed around two basic assumptions: relays are

Forward prediction of FSO received signal for FSO/RF hybrid network
2009 International Workshop on Satellite and Space Communications, 2009The benefits of Free space Optics (FSO) motivates to use it for future high data rate demanding communication applications. However, widespread growth of the technology has been hampered by reduced availability due to weather influences on the link. The alternate is to use back up RF link for improving the availability.

Memory Decoding Algorithm for FSO Transmission
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020Due to the limitation of the radio frequency (RF) spectrum, it is increasingly more difficult to support billions of wireless devices in the age of Internet-of-Things. Consequently, many recent wireless indoor communication systems have been developed using free space optical (FSO) communication technologies that exploit the extremely large light ...

This paper studies the possibility of using axicons in free space optics (FSO) systems. The behavior of the pseudo- Bessel beams generated by "logarithmic" and "linear" axicons, with or without stops, was analyzed through the Huygens-Fresnel integral of diffraction in cylindrical coordinates.

Adaptive coded modulation for FSO links
2012 8th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2012The terrestrial free space optical (FSO) link promises a number of advantages in terms of higher data rates and license free bandwidth, but is challenged by atmospheric propagation conditions. Designing a system for the worst channel conditions leads to an inadequate use of resources while opting for a system design based on clear sky conditions lacks ...
