This article presents an overview of optical wireless (OW) communication systems that
operate both in the short-(personal and indoor systems) and the long-range (outdoor and …

Optical wireless communication (OWC) using intensity-modulation and direct-detection
(IM/DD) has a channel model which possesses unique features, due to the constraints …

We propose an optical wireless indoor localization using light emitting diodes (LEDs) and
demonstrate it via simulation. Unique frequency addresses are assigned to each LED lamp …

We examine multiple-subcarrier modulation (MSM) schemes for wireless infrared digital
communication in the indoor environment. Intensity modulation with direct detection (IM/DD) …

We have experimentally characterized nondirected indoor channels that use intensity
modulation and direct detection of an infrared carrier at a wavelength of 832 nm. At several …

White LEDs are set to penetrate many areas of everyday life. An interesting property of these
devices (in addition to their lightening capabilities) is that they can be utilised for data …

In this paper, we present a hybrid asymmetrically clipped optical orthogonal frequency
division multiplexing (OFDM) system. This system uses a combination of asymmetrically …

Wireless infrared transmission systems for indoor use are affected by noise and interference
induced by natural and artificial ambient light. This paper presents a characterisation …

An apparatus and method is provided for transparent com munication between a remote or
mobile device and a fixed communication host network. The apparatus and method may …

The channel model for indoor wireless optical communication links is unusual in that it
combines the intensity-modulation constraints of the Poisson photon-counting channel with …
