Prototyping and Real Time Testing of Underwater Acoustic Modem

Home The aim of our senior design project is to prototype and test a stand-alone

Members underwater acoustic modem, based on existing multicarrier modem designs

Project Proposal tested mainly in a lab environment. Important aspects are signal amplification and

Project Statement system modularization. With signal amplification, we would be able to transmit the

Presentation signal for a range of almost 200 meters as opposed to the previous tests of

Final Report distance about 1 meter. With system modularization, we would be able to perform

Presentation_video.zip real time tests of the stand-alone modem in the lakes, rather than in the tanks. In

Weekly Updates the demonstration, a transmitter implemented in a DSP board is programmed to

Pictures send data every 20sec. There are two receivers to be demonstrated, the first one

uses Matlab programs on a laptop, while the second one is based on a DSP

board containing all the system software. The DSP board, a power amplifier,

batteries, and an underwater transducer/hydrophone are placed in a waterproof

casing.
