Visible Light Communications
Visible light communication (VLC) is an optical wireless communication technology that uses low-power light-emitting diodes (LEDs) to not only provide light, but also broadcast data [1–3]. LEDs are extremely energy-efficient and are expected to become widespread in general lighting applications. Because LEDs are solid-state lighting devices, they can be modulated at high speed compared to other...
متن کامل"Lights-off" visible light communications
– In order to implement visible light communications (VLC) through indoor lighting, a set of challenges arise due to conflicting requirements from the two missions. In this paper we examine one of these challenges: how to communicate when the lights are " off. " We investigate VLC with limits on transmit power, which we define to be low enough so that users will accept that the lights are in th...
متن کاملSystems biology: will it work?
Systems biology describes the collection of a set of measurements on a system, integrated with a mathematical model of that system. The model and the measurements must be made together and refined iteratively, requiring close collaboration between biologists and modellers. A complete cell is probably too large and complicated to model yet, but simplified subsystems will probably produce valuabl...
متن کاملAsynchronous indoor positioning system based on visible light communications
Indoor positioning has become an attractive research topic within the past two decades. However, no satisfying solution has been found with consideration of both accuracy and system complexity. Recently, research on visible light communications (VLC) offer new opportunities in realizing accurate indoor positioning with relatively simple system configuration. An indoor positioning system based o...
متن کاملCoded Modulation with APSK for OFDM-Based Visible Light Communications
Coded modulation with APSK is proposed for OFDM-based VLC systems. Simulation results show that the proposed scheme achieves better performance than conventional QAM counterpart in both DCO-OFDM and ACO-OFDM systems, while similar complexity is maintained. OCIS codes: (060.2605) Free-space optical communication; (060.4080) Modulation.
