Visible light communication (VLC) using light-emitting-diodes (LEDs) has been a popular research area recently. VLC can provide a practical solution for indoor positioning. In this paper, the impact of multipath reflections on a two-dimensional indoor VLC positioning is investigated, considering a complex indoor environment with walls, floor, and ceiling. For the proposed positioning system, an LED...
Visible Light Communication (VLC) technology using light emitting diodes (LEDs) has been gaining increasing attention in recent years as it is appealing for a wide range of applications such as indoor positioning. Orthogonal frequency division multiplexing (OFDM) has been applied to indoor wireless optical communications in order to mitigate the effect of multipath distortion of the optical channel...
Multipath-induced dispersion is one of the major concerns for complex indoor environments affecting the positioning accuracy. This paper investigates the impact of multipath reflections numerically on the VLC positioning systems. Power distribution is first calculated, then the positioning accuracy in terms of root mean square (RMS) error is analyzed.
