Optimal Modulation Technique for Underwater Visible Light Communication Using Rolling-Shutter Sensor
Publikováno v:
IEEE Access, Vol 9, Pp 146422-146436 (2021)
The visible light communication (VLC) technique using a rolling-shutter sensor-based commercial camera has an advantage in that the LED and camera mounted on an underwater device (e.g., drone, sensor) can be effectively used as a transmitter (Tx) and
