Abstract
We propose a new indoor positioning system utilizing visible light communication.
Intensity modulation/direct detection and carrier allocation methods are utilized
in the proposed system. Simultaneous three channel transmissions were applied
to calculate the receiver's position. The characteristics of the proposed
positioning system were investigated through simulation based on the experimental
results, and the feasibility of the proposed system was verified by experimentation.
The experimental result shows that the average error of estimated positions
is reduced to 2.4 cm using adjustment process by normalizing method, which
is compared with 141.1 cm without adjustment process.
