Calibration of Visible Light Positioning Systems with a Mobile Robot. [PDF]

open access: yesSensors (Basel), 2021
Most indoor positioning systems require calibration before use. Fingerprinting requires the construction of a signal strength map, while ranging systems need the coordinates of the beacons. Calibration approaches exist for positioning systems that use Wi-Fi, radio frequency identification or ultrawideband.

Joint Visible Light Communications and Positioning with Dimming

open access: yes2023 31st Signal Processing and Communications Applications Conference (SIU), 2023
In this paper, a novel visible light communication (VLC) and three-dimensional (3D) positioning (VLP) algorithm based on spatial modulation (SM) with dimming capability is proposed. With the help of the signal and pilot symbols observed by a user with two photodetectors (PD) on the receiver, the detection of the transmitted data with the estimated ...
