A test bench for a VLP system using CDMA as Multiple Access Technology

In this paper, we present a test bench for a Visible Light Positioning (VLP) system using Code Division Multiple Access (CDMA). A VLP system should be easy and low cost to install in existing infrastructures meaning there is no backbone network between the LEDs. CDMA can therefore be used as multiple access technology, with the challenging observation that the LEDs are transmitting data in a non-synchronized way to the receiver. Because the VLP...
