Time reversal (TR) exploits spatial diversity to achieve spatial and temporal focusing in
complex environments. Over the last decade, the TR concept has been applied successfully …

Underwater wireless communication techniques have played the most important role in the
exploration of oceans and other aquatic environments. Underwater acoustic (UWA) …

In recent years, underwater acoustic (UWA) communications have received much attention
as their applications are beginning to shift from military towards commercial. UWA …

Systematic measurements were performed to characterize shallow-water acoustic
propagation channels for applications in the field of underwater communications. The survey …

The purpose of this paper is to develop a decision-feedback equalizer (DFE) using a fixed
set of parameters applicable to most shallow oceans with minimal user supervision (ie, a …

The spatial and temporal focusing properties of time-reversal methods can be exploited for
undersea acoustic communications. Spatial focusing mitigates channel fading and produces …

In this chapter, we discuss acoustic communication methods which are used to provide
wireless connection between remote nodes operating in an underwater environment. We …

Direct-sequence spread-spectrum signals collected from the TREX04 experiment are
analyzed to determine the bit-error-rate (BER) as a function of the input signal-to-noise ratio …

Equations are derived for analyzing the performance of channel estimate based equalizers.
The performance is characterized in terms of the mean squared soft decision error (σ s 2) of …
