Vehicle-to-Vehicle Optical Wireless Communication with the Smart Corner ? Automotive Headlamp

摘要

Optical wireless communication (OWC) is seen as an interesting technology to complement radio-based systems for vehicular communication. Along with sensors like radar, lidar or cameras, vehicular communication is a cornerstone of the future autonomous vehicles. Automotive Lighting - Magneti Marelli has thus gathered all these technologies into a single automotive light called Smart Corner?. This paper details the architecture, integration and performances of the OWC system used in the third generation Smart Corner?presented at the 2019 Consumer Electronic Show (CES). Based on an orthogonal frequency division multiplexing (OFDM) modulation combined with channel estimation and bit loading, this system maintains a null packet error rate (PER) over 2 m at more than 100 Mbps and over 15 m at 14 Mbps, which shows it could provide a vital redundant communication link in several automotive use cases.
