Fuzzy-analytical power allocation based on SNR and balanced BER in free-space optical communication

Journal of Engineering and Applied Science
In recent studies on free-space optical communication, researchers have focused on improving data transmission speed. Optimizing resource management, including power allocation, in free-space optical communication enhances the number of bits received at ...

Higher dimensional quantum communication in a curved spacetime: an efficient simulation of the propagation of the wavefront of a photon

, 2018
A photon with a modulated wavefront can produce a quantum communication channel in a larger Hilbert space. For example, higher dimensional quantum key distribution (HD-QKD) can encode information in the transverse linear momentum (LM) or orbital angular ...

On Applications of Disruption Tolerant Networking to Optical Networking in Space [PDF]

, 2012
The integration of optical communication links into space networks via Disruption Tolerant Networking (DTN) is a largely unexplored area of research. Building on successful foundational work accomplished at JPL, we discuss a multi-hop multi-path network ...

Hybrid Deep Learning-Based Adaptive Modulation for Free Space Optical (FSO) Communication

IEEE Access
Throughput values are closer to the required values of some current wireless systems, and free-space optics (FSO) has several promising applications in scenarios where high bandwidth demand necessitates a low-cost electronic warfare (EW) strategy.

Lasers for free-space optical communications

III-Vs Review, 2001
AbstractFree-space optics (FSO) - or telecoms systems based on free space lasers (FSLs) - have attractions as an alternative to existing signal conduits such as fibre or wireless. They offer high data rates (about 1 Gb/s) and can be as much as a fifth the cost of underground fibre.
