High data rate multiple input multiple output (MIMO) optical wireless communications using white led lighting
Lubin Zeng,Dominic O'Brien,Hoa Minh,Grahame Faulkner,Kyung-Woo Lee,Daekwang Jung,Yun-Je Oh,Eun Tae Won +7 more
TL;DR: In this paper, a non-imaging optical MIMO system does not perform properly at all receiver positions due to symmetry, but an imaging based system can operate under all foreseeable circumstances, and simulations show such systems can operate at several hundred Mbit/s, and up to G Bit/s in many circumstances.
Journal ArticleDOI
A 3-Gb/s Single-LED OFDM-Based Wireless VLC Link Using a Gallium Nitride $\mu{\rm LED}$
Dobroslav Tsonev,Hyunchae Chun,Sujan Rajbhandari,Jonathan J. D. McKendry,Stefan Videv,Erdan Gu,Mohsin Haji,Scott Watson,Anthony Kelly,Grahame Faulkner,Martin D. Dawson,Harald Haas,Dominic O'Brien +12 more
TL;DR: In this article, the authors presented a visible light communication (VLC) system based on a single 50-μm gallium nitride light emitting diode (LED) with a 3-dB modulation bandwidth of at least 60 MHz.
Journal ArticleDOI
100-Mb/s NRZ Visible Light Communications Using a Postequalized White LED
Hoa Le Minh,Dominic O'Brien,Grahame Faulkner,Lubin Zeng,Kyung-Woo Lee,Daekwang Jung,Yun-Je Oh,Eun Tae Won +7 more
TL;DR: In this paper, a high-speed visible light communications link that uses a white-light light-emitting diode (LED) was described, and a data rate of 100 Mb/s was achieved using on-off keying non-return-to-zero modulation.
Journal ArticleDOI
A Gigabit/s Indoor Wireless Transmission Using MIMO-OFDM Visible-Light Communications
TL;DR: An experimental demonstration of indoor wireless visible-light communication transmission at 1 Gb/s is reported, using a four-channel multiple-input multiple-output link that uses white LED sources.
Proceedings ArticleDOI
Visible light communications: Challenges and possibilities
TL;DR: The basic components in visible light communications systems are outlined, the state of the art is reviewed and some of the challenges and possibilities for this new wireless transmission technique are discussed.
