Protocols 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 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 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 کاملMulticarrier Relay Selection for Full-Duplex Relay-Assisted OFDM D2D Systems
In this paper, we propose a full-duplex orthogonal frequency-division multiplexing (OFDM) deviceto-device (D2D) system in two-hop networks, where multiple full-duplex decode-and-forward (DF) relays assist the transmission from D2D user equipment (DUE) transmitter to DUE receiver. By such a transmission mechanism, the signal transmitted by the DUE transmitter does not need to go through a base s...
متن کاملFree-space quantum network with trusted relay
Nowadays, information security plays an increasingly important role in global communication. Quantum cryptography [1, 2], particularly quantum key distribution (QKD), offers means to expand a secure key between two distant parties, whose security is stemmed from the fundamental laws of quantum mechanics [3–5]. In practice, QKD experiments have been demonstrated over longdistance optical links t...
