Camera Parameters Division Multiplexing Signal Transmission for Optical Camera Communication

Optical Camera Communication (OCC) is an emerging wireless communication technology. It enables data transfer between light sources such as LEDs and the CMOS image sensors of cameras. Existing work has focused on improving the communication performance as regards data rate and bit error rate. However, there has been no study on the simultaneous transmission of different information from a single transmitter to multiple receivers with different camera parameters. Therefore, this paper proposes a Camera Parameters Division Multiplexing (CPDM) signal transmission for OCC. The goal of the CPDM is to multiplex optical signals to different receiver cameras using a single transmitter. The feasibility of the proposed CPDM is demonstrated through first experimental results. We have also evaluated the phase shift tolerance to confirm the simultaneous multi-receiver communication OCC.
