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 …

A blend of introductory material and advanced signal processing and communication
techniques, of critical importance to underwater system and network development This book …

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

Underwater acoustic channels are fast varying spatially and temporally according to
environmental conditions. Adaptive modulation and coding (AMC) is appealing for …

Underwater communication is crucial for subsea engineering. Currently, although a variety
of available technologies are available for underwater communication, almost all of them are …

Superposition coding (SC) is a nonorthogonal scheme for downlink communications, in
which all users are allowed to use the full degrees of freedom of the channel and successive …

An underwater acoustic network simulation methodology is presented that is based on
lookup tables (LUTs) with physical-layer error ratios. These LUTs are prepared with a …

A low-complexity receiver is proposed for high-frequency underwater acoustic multiple-input-
multiple-output (MIMO) channels. The receiver uses time reversal combining followed by a …

In this paper, we present a sparse channel estimator that exploits channel coherence across
blocks for orthogonal frequency division multiplexing (OFDM) in underwater acoustic (UWA) …

Channel estimation plays a crucial role in Internet of Underwater Things networks.
Traditional channel estimation algorithms have limited performance improvement under the …
