Optical CDMA-based wireless indoor positioning through time-of-arrival of light-emitting diodes

We propose a novel visible light wireless indoor positioning scheme based on optical-code-division multiple-assess (OCDMA) and time-of-arrival (TOA) principle. A set of three light-emitting diodes (LEDs) ceiling light fixtures are utilized to transmit their location information to a device, equipped…
