Abstract: Visible-light communication (VLC) is an optical wireless communication technique that uses light emitting diodes (LEDs) or other optical sources to transmit information to a user equipment (UE) device. An optically-based location determination approach, such as using VLC infrastructure, can meet a desire for location-based services where use of VLC can provide a solution to an indoor localization or navigation problem. A fingerprinting approach can include use of an optical received signal strength (RSS) or other information (e.g., an image of a scene) to generate a spatial fingerprint map of an area. A later-received RSS on the UE device and the prior-generated fingerprint map representative of RSS can be received, and a fingerprint map and RSS observations can be provided as inputs to a Bayesian filter, such as an Extended Kalman Filter (EKF) or a Particle Filter, to provide an estimated position for the UE device.
