Vehicle-to-Vehicle Optical Camera Communications for Platoon Verification

IEEE Wireless Communications and Networking Conference
In autonomous platooning, multiple vehicles on the road are using vehicle-to-vehicle (V2V) communications to follow each other. They are able to accelerate and decelerate simultaneously at a reduced safety distance.

Sub-column pixel neural network scheme for modulation format shifting based optical camera communications.

Optics Letters, 2022
In this Letter, a sub-column pixel neural network (SCPNN) scheme is proposed to label the pixel patterns in modulation format shifting based optical camera communication (MFS-OCC) systems. The MFS scheme, by identifying on-off keying (OOK) and Manchester

Practical design of Screen-to-Camera based Optical Camera Communication

2015 International Conference on Information Networking (ICOIN), 2015
This paper introduces the Optical Camera Communication (OCC) based on Computer Vision. The practical issues of implementation of the asynchronous communication based Screen-to-Camera are performed. The asynchronous scheme proposed by our previous work is modified to be simple, suitable and reliable in order to apply in case of heterogeneous frame rate ...

Camera and Inverse Camera System for Free-Space Optical Communications

Frontiers in Optics / Laser Science, 2018
We introduce an imaging-based transceiver for FSOC that enables precision beam steering over a wide field-of-regard using low-cost components with no moving parts. Passive beam steering provides dynamic beam-shaping and multiplexable communication.

Nearest neighbor bit assisted decision scheme for ISI mitigation in optical camera communications.

Optics Letters
To enable a higher transmission rate in optical camera communication (OCC) systems, severe inter-symbol interference (ISI) occurs owing to the reduction of the number of pixel-row-per-bit (PPB).
