Long-range time reversal communication in deep water: Experimental results

Abstract

In December 2011 a long-range acoustic communication experiment was conducted in deep water, west of Izu-Ogasawara Islands, Japan. The experiment involved a stationary source (450–550 Hz) and an 18-element vertical array (102-m aperture), both deployed at around the sound channel axis. Initial analysis of data demonstrates that a data rate of 400 bits/s can be achieved over ∼600-km range in deep water using 16 quadrature amplitude modulation and passive time reversal equalization.
