Visible light positioning

Planar positioning bias due to transmitter and receiver tilting in RSS-based ranging VLP

In this work, a set of general expressions treating both transmitter and receiver tilt in received signal strength based visible light positioning is elaborated. A meticulous approach involving Euler rotations leads to a compact expression for the …

A positioning algorithm for VLP in the presence of orientation uncertainty

As the positioning accuracy of a visible light positioning (VLP) system is highly susceptible to changes in the orientation of the receiver, accurate knowledge of the receiver orientation is required. In practice, the orientation of the receiver is …

Magnitude of the distance estimation bias in received signal strength visible light positioning

In several works, statistical precision of distance estimators in visible light positioning was studied by evaluating the Cramer-Rao lower bound, assuming that the estimator is unbiased. Here, it is demonstrated that the maximum likelihood estimator …
