Optical beam position estimation in free-space optical communication

IEEE Transactions on Aerospace and Electronic Systems, 2016
The position of the optical beam on an optical detector array is an important parameter for optimal decoding in free-space optical communication systems; thus, its accurate estimation is essential. In this paper, the performance of three estimators (maximum likelihood, center of gravity, and template matching) for the estimation of center of the beam ...

Channel estimation for free-space optical communication

IEEE Conference on Decision and Control and European Control Conference, 2011
Optical fade caused by atmospheric turbulence impairs the performance of optical communication through atmosphere. Adaptive techniques of signal detection, power control, and channel coding can be employed to reduce the degrading effect of this phenomenon. For implementation of these techniques, the knowledge of channel state is required.

Free Space Optical Communications (FSO)

2007 IEEE Avionics, Fiber-Optics and Photonics Technology Conference, 2007
Free space optical communications (FSO) is now common for point to point communications between fixed locations on land, and is also used for communication between moving platforms on land, on the surface of the sea, in air, and in space. Free space implies that it is not practical to use optical fiber to connect the points that need to communicate or ...

Adaptive optics for free space optical communication

Optique adaptative pour les télécommunications optiques Les télécommunications optiques en espace libre sont capables d'autoriser des débits de plusieurs dizaines de gigabits par seconde. Pour traiter ces débits en bénéficiant des techniques développées dans le cadre de l'optique fibrée, il est souhaitable d'injecter le faisceau reçu ...
