Image-sensor-based visible light communication for automotive applications
Takaya Yamazato,Isamu Takai,Hiraku Okada,Toshiaki Fujii,Tomohiro Yendo,Shintaro Arai,Michinori Andoh,Tomohisa Harada,Keita Yasutomi,Keiichiro Kagawa,Shoji Kawahito +10 more
TL;DR: Characteristics unique to image-sensor-based VLC as compared to radio wave technology are identified to improve automotive safety and demonstrate its effectiveness through a V2V communication field trial.
Journal ArticleDOI
A New Automotive VLC System Using Optical Communication Image Sensor
Yuki Goto,Isamu Takai,Takaya Yamazato,Hiraku Okada,Toshiaki Fujii,Shoji Kawahito,Shintaro Arai,Tomohiro Yendo,Koji Kamakura +8 more
TL;DR: To reach a transmission performance of 54 Mb/s, which is standardized as the maximum data rate in IEEE 802.11p for V2X communication, a more advanced OCI-based automotive VLC system is described, which achieves a more than fivefold higher data rate by introducing optical orthogonal frequency-division multiplexing (opticalOFDM).
Journal ArticleDOI
Vehicle Motion and Pixel Illumination Modeling for Image Sensor Based Visible Light Communication
Takaya Yamazato,Masayuki Kinoshita,Shintaro Arai,Eisho Souke,Tomohiro Yendo,Toshiaki Fujii,Koji Kamakura,Hiraku Okada +7 more
TL;DR: This paper describes and provides results for modeling image sensor based VLC for automotive applications and shows that a single-pinhole camera model can be applied to vehicle motion modeling of a I2V-VLC, V2I-V LC, and V2V -VLC.
Proceedings ArticleDOI
Experimental on Hierarchical Transmission Scheme for Visible Light Communication using LED Traffic Light and High-Speed Camera
Shintaro Arai,S. Mase,Takaya Yamazato,T. Endo,Toshiaki Fujii,Masayuki Tanimoto,Kiyosumi Kidono,Yoshikatsu Kimura,Yoshiki Ninomiya +8 more
TL;DR: The proposed hierarchical transmission schemes outperform the conventional on-off keying and the reception of high priority data is guaranteed even LED-camera distance is further.
Proceedings ArticleDOI
High-speed transmission of overlay coding for road-to-vehicle visible light communication using LED array and high-speed camera
TL;DR: This paper aims to improve the visible light communication system using LED array and high-speed camera by proposing what is called “overlay coding”, a new coding method to realize a hierarchical coding, through which a high-priority data can be received even if the receiver is far from a transmitter.
