Description
A detailed study of a novel method for high-speed acoustic communications in ports and
shallow water is presented. A series of field experiments, coupled with simulated results
using an acoustic channel model have been conducted to outline the optimal modulation
schemes for use in the highly reverberant and Doppler dominated shallow water
acoustic channel. Field experiments were conducted in the vicinity of the SeaTech
marina and the Port Everglades turning basin in water depths of 2 to 15 meters and
ranges of between 25 and 75 meters. An automated FAU acoustic modem transmitted
BPSK and QPSK modulated messages centered at 300 kHz, with a source level of 173
dB re 1pPa and a symbol bandwidth of 25, 50 or 75 kHz. The coded rate varied from
25000 to 150000 bits per second. These high data rates are made possible using a high
resolution Decision Feedback Equalizer with an efficient Doppler compensation process.
The results of this study demonstrate the ability of such a system to transmit video
images in a shallow water environment.
