Abstract Recent advancements in Solid State Lighting (SSL) have triggered research in the
domain of Visible Light Communication (VLC) which enables us to use Light Emitting …

The use of infrared radiation as a medium for high-speed short-range wireless digital
communication is discussed. Available infrared links and local-area networks are described …

The use of optical free-space emissions to provide indoor wireless com-nications has been
studied extensively since the pioneering work of Gfeller and Bapst in 1979 [1]. These studies …

We show that realistic multipath infrared channels can be characterized well by only two
parameters: optical path loss and RMS delay spread. Functional models for the impulse …

We examine the use of differential pulse-position modulation (DPPM) for optical
communication systems using intensity modulation with direct detection in the presence of …

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 …

We explore the use of the spatial domain as a degree of freedom for data encoding and
channel hopping. We experimentally demonstrate data encoding at 20?? Gbit/s using four …

For future short-range applications, optical wireless communications present a viable and
