Indoor positioning algorithm using light- emitting diode visible light communications
This paper proposes a novel indoor positioning algorithm using visible light communications (VLC). The algorithm is implemented by preinstalled light-emitting diode illumination systems. It recovers the VLC channel features from illuminating visible light and estimates receiver locations by analytically solving the Lambertian transmission equation group. According to our research, the algorithm...
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...
