Abstract

This thesis demonstrates an underwater optical wireless communication transmitter. The

transmitter has been designed to make it easy to add on to any system, while having a minimal

impact on project power and cost budgets. The hardware designed for this thesis is capable of

transmitting at speeds up to 8.88 Mbps with bit error ratios on the order of 10^−5 to 10^−2 at a

received optical power from -19.2 to -27.5 dBm. The transmitter consumes 1.75 W of power and

has a bill of materials cost of $41.95. This thesis demonstrates the transmission of a 720p, one

frame-per-second video with a simple RS(255,223) encoding.
