Underwater Acoustic Communication Using Time-Reversal Self-Equalization

摘要

Although there has been some progress in overcoming the time-varying dispersion that can destroy coherent digital information, fast and reliable data rates have remained elusive. Time reversal was applied to the communications problem and shown to be an effective technique to counter the inter-symbol interference caused by multipath dispersion. A substantial advantage of time- reversal, self-equalization over one-way single source communication and to a lesser extent, one-way broadside (nearly single mode) communication, was demonstrated.
