چکیده
Abstract In this paper, the adaptive time reversal (ATR) technique combined with a single channel decision feed back equalizer (DFE) is applied to an at-sea experiment of underwater acoustic multiple-input/multiple-output (MIMO) communication utilizing signal bandwidth 4.5-8.5 kHz over distance 12.5 km. We focus on demonstration effectiveness ATR-DFE schemes for MIMO in real sea environment, and how much data rate could be achieved, changing parameters. It also investigated influences variation performances. Finally, relationship between effective bit error (BER) evaluated. As result, tens kbps achieved practical BER by ATR-DFE, it can said that performance would remarkable considering communication.

Experimental Demonstration of Long-Range Underwater Acoustic Communication Using a Vertical Sensor Array
This paper proposes a composite channel virtual time reversal mirror (CCVTRM) for vertical sensor array (VSA) processing and applies it to long-range underwater acoustic (UWA) communication in shallow water. Because of weak signal-to-noise ratio (SNR), it is unable to accurately estimate the channel impulse response of each sensor of the VSA, thus the traditional passive time reversal mirror (P...
متن کاملLong-range time reversal communication in deep water: experimental results.
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 dee...
متن کاملAn Initial Demonstration of Underwater Acoustic Communication Using Time Reversal
In July 1999, an at-sea experiment to measure the focus of a 3.5-kHz centered time-reversal mirror (TRM) was conducted in three different environments: an absorptive bottom, a reflective bottom, and a sloping bottom. The experiment included a preliminary exploration of using a TRM to generate binary-phase shift keying communication sequences in each of these environments. Broadside communicatio...
