This paper presents a comprehensive survey on acquisition, tracking, and pointing (ATP)
mechanisms used in free-space optical (FSO) communications systems. ATP mechanisms …

The field of visible light communications (VLC) has gained significant interest over the last
decade, in both fibre and free-space embodiments. In fibre systems, the availability of low …

The 2nd Edition of Optical Wireless Communications: System and Channel Modelling with
MATLAB® with additional new materials, is a self-contained volume that provides a concise …

As we step further into the 21st century, the demand for sustainable energy-efficient
technology grows higher. The important area of electric lighting, currently dominated by …

White lighting LEDs offer great potential for high speed communications, especially for
indoor applications. However, for their widespread adoption, two important issues need to …

In order to circumvent radio spectrum congestion, we propose an innovative system which
can provide multiple infrared optical wireless beams simultaneously where each beam …

Visible Light Communication (VLC) has gained great interest in the last decade due to the
rapid developments in Light Emitting Diodes (LEDs) fabrication. Efficiency, durability and …

An overview of the developments in optical wireless systems viewed from the traditional
communications viewpoint of transmitter, channel and receiver is presented. The trends in …

A high-performance blue filter was demonstrated and employed to increase the modulation
bandwidth and dramatically reduce the bit error rate of a white-LED-based VLC system. It …

We compare narrow and wide laser beams in a free-space optical (FSO) communications
system for high-speed train communications and analyze the tradeoffs among the received …
