This Small Business Innovation Research (SBIR) Phase II project aims to develop a real-time high-data-rate multicarrier underwater acoustic modem for aquatic applications. The modem to be developed will achieve a data rate that is more than one order of magnitude higher than all competing commercial products in challenging shallow water environments. It will have robust error performance in the presence of impulse-like noise and undesired disruptions. In addition, the modem will be power efficient to sustain long operation time, have a user-friendly interface, and maintain an easily-extendable architecture to facilitate advanced networking functionalities. Bringing the advanced multicarrier technology into the underwater modem market, this project solves one long-standing problem in the field, i.e., making multicarrier modulation work in underwater channels (earlier attempts all had only limited success). With one order of magnitude data rate increase, this project will significantly advance the state-of-the-art in underwater telemetry.
