Relay-Assisted Free-Space Optical Communications
The atmospheric lightwave propagation is considerably influenced by the random variations in the refractive index of air pockets due to turbulence. This undesired effect significantly degrades the performance of free-space optical (FSO) communication systems. Interestingly, the severity of such random degradations is highly related to the range of atmospheric propagation. In this thesis, we int...
متن کاملProtocols for Relay-Assisted Free-Space Optical Systems
We investigate transmission protocols for relay-assisted free-space optical (FSO) systems, when multiple parallel relays are employed and there is no direct link between the source and the destination. As alternatives to all-active FSO relaying, where all the available relays transmit concurrently, we propose schemes that select only a single relay to participate in the communication between th...
متن کاملRelay Assisted Hybrid Free Space Optical Systems : a Survey
Volume 6, Issue 7, July 2017 Page 209 ABSTRACT The Free Space Optical communication is an ideal solution for exponentially growing demands of high bandwidth and high data rates for modern era communication. In present scenario, its popularity getting momentum because of large bandwidth, license free spectrum, high data rate, absence of radiation hazards, easy and quick installation, immunity to...
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 کاملCooperative 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 ...
