Visible light positioning and communication cooperative systems

A cooperative system for visible light positioning (VLP) and visible light communication (VLC) is proposed based on the spread-spectrum plugin of optical identification (OPID). By keeping the existing VLC frame structure untouched, two different implementation schemes were designed by adding the location information field into the communication information field for VLP applications. It is deemed to be a good solution to overcome the mutual exclusion between VLP and VLC systems.
