Recently, a camera or an image sensor receiver based optical wireless communications
(OWC) techniques have attracted particular interest in areas such as the internet of things …

The relay positions or hop distances in a multi-hop relaying scheme is an important
parameter that can be optimized in order to mitigate the angle-of-arrival variance or pointing …

Due to their flexibility and low cost deployment, unmanned aerial vehicles (UAV) will most
likely act as base stations and backhaul relays in the next generation of wireless …

Free-space optical (FSO) communications will play an important role in the backhaul of
future generation of wireless networks in order to support high data rates. Because of narrow …

Pointing and acquisition are an important aspect of free-space optical communications
because of the narrow beamwidth associated with the optical signal. In this paper, we have …

Photon counting detector arrays are commonly used for free-space optical communications
in deep space. Such detector arrays-by virtue of their size-help in the collection of the optical …

The centroid estimation of the beacon spot is crucial to the pointing, acquisition, and tracking
subsystem in inter-satellite optical wireless communication (IsOWC), especially for the …

Optical beam position on a detector array is an important parameter for optimal symbol
detection in a free-space optical communication system; hence it is essential to accurately …

An array of detectors is widely used in deep space optical communications for both fine
