Experimental demonstration of a 10BASE-T Ethernet visible light communications system using white phosphor light-emitting diodes
In this study, a compact design of a highly efficient, and a high luminosity light-emitting diode (LED)-based visible light communications system is presented, which is capable of providing standard room illumination levels and also widecoverage Ethernet 10BASE-T optical wireless downlink communications over a distance of 2.3 m using commercial white light phosphor LEDs. The measured signal-to-...
متن کاملVisible 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 کاملOptical Adaptive Precoding for Visible Light Communications
Multiple-input multiple-output (MIMO) techniques have recently demonstrated significant potentials in visible light communications (VLC), as they can overcome the modulation bandwidth limitation and provide substantial improvement in terms of spectral efficiency and link reliability. However, MIMO systems typically suffer from inter-channel interference, which causes severe degradation to the s...
متن کاملSCMA with Low Complexity Symmetric Codebook Design for Visible Light Communication
Abstract—Sparse code multiple access (SCMA) is attracting significant research interests currently, which is considered as a promising multiple access technique for 5G systems. It serves as a good candidate for the future communication network with massive nodes due to its capability of handling user overloading. Introducing SCMA to visible light communication (VLC) can provide another opportun...
