Underwater Visible Light Communication: SubLC for L3Harris
Overview
Our project is the design of an underwater visible light communications system that will function under the use of a PynqZ2 FPGA as the transmitter and receiver. Our system allows the user to view the data being transferred between both contact points. The data that is transferred will be sensor data including factors such as water temperature, water pressure, salt concentration, chlorophyll concentration, and a video feed. The light communication systems function using a pulsating blue-light LED with the receiver being a photodiode. The goal is a transmission rate of higher than 10 Mbps and a bit error rate below 2x10^-5.
Community Benefit
Visible light communications have long been studied for the use of underwater exploration. With the inherently noisy environment and low sunlight permeability, visible light communication can provide a way to allow constant communication between submarines and buoys, with data transmitting at a higher rate than ever before.
