State estimation and motion tracking for spatially diverse VLC networks

Improvements in solid-state/LED lighting are driving increased capabilities of lighting systems - offering potential for applications such as Visible Light Communications (VLC) and indoor localization using the lighting medium. In this paper, we motivate the adoption of localization for both the support of handover between arrays of VLC-equipped luminaires as well as for indoor positioning and beam steering. Our approach uses a state estimation model to achieve localization and motion tracking in spatially diverse VLC networks while considering user mobility and dynamic device orientation. Under these conditions, we show simulation results with location and velocity errors of 5cm and 10cm/s, respectively.
