Abstract: |
To address the limitations of underwater acoustic wave propagation, we propose a paradigm
shift in how information is carried over short-range (tens of meters) acoustic links. We suggest
the study -and then development- of a novel carrierless ultrasonic transmission and multiple
access technique. Short, properly designed/shaped pulses are transmitted in the ultrasonic
spectral regime following an adaptive time-hopping pattern with a superimposed
adaptive spreading code. The effect is nearly seamless physical/MAC layer integration, potential
for highest data rate communication by properly optimized spreading sequences, and
LPD/LPI operation via low-power transmission. Analysis of the supported bit rates versus
LPD/LPI performance characterization will be carried out as a function of range. Secondary
-yet important- benefits of the proposed approach are low cost and weight oscillator-free transducers
and excellent receiver interference suppressing capabilities along the well documented
theory and practice of spread-spectrum signal reception. Net-Tune Technologies investigators
(Dr. Tommaso Melodia and Dr. Dimitris Pados) are partnering with the State University of
New York at Buffalo (academic institution subcontractor Prof. Stella Batalama) and Teledyne-
Benthos (Chief Scientist Dale Green as consultant) to form a most experienced and qualified
team to explore for the first time -to the very best of our knowledge- this new technical avenue
toward 500Kbps or more communication across 100m or more underwater distances. |
Benefits: |
The proposed technology will benefit undersea applications requiring high data rates over short ranges (10-100m). This may include surveillance applications, communications among UAVs and UUVs and other underwater robots, underwater video and telephony applications over short ranges. |
