Miller code usage in Visible Light Communications under the PHY I layer of the IEEE 802.15.7 standard

This paper approaches the issues concerning the usage of the delay modulation as a coding technique used for outdoor Visible Light Communications (VLC) under PHY I layer of the IEEE 802.15.7 standard. We perform a comparative analysis between the Manchester code, as a traditional code, specified by the upper mentioned standard and the Miller code as a possible candidate for outdoor MIMO applications. Simulation and experimental results are provided, offering an overview over the multi-channel, flickering and Bit Error Ratio (BER) performances.
