Overlay coding in vehicle visible light communication using multiple exposures

摘要

This paper proposes an overlay coding in vehicle visible light communication using high speed cameras. The short range and long range data are overlaid to be transmitted simultaneously in the same LED array. Two cameras with different exposure time setting are used to receive the two data streams. Simulation results show that by using the proposed overlay coding, both the short and long range signal can be transmitted and received with low bit error rate.
