Ocean and water basically cover the major parts of our planet. To obtain the best utilization
of the underlying resources on these parts of the Earth, people have made some research …

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 acoustic communication is a core enabling technology with applications in
ocean monitoring using remote sensors and autonomous underwater vehicles. One of the …

Present-day mobile communications systems can be classified as fixed-to-mobile because
they allow mobility on only one end (eg the mobile phone to a fixed mobile operator's cell …

During the July 2003 acoustic communications experiment conducted in 100 m deep water
off the western side of Kauai, Hawaii, a 10 s binary phase shift keying signal with a symbol …

We propose a new method of modeling the signal transmission in underwater acoustic
communications when the transmitter and receiver are moving. The motion-induced channel …

This paper studies adaptive transmission in an underwater acoustic (UWA) point-to-point
communication system that operates on an epoch-by-epoch basis for a long term. A fixed …

A realistic 2-D time-evolving ocean surface model has been combined with an existing
acoustic ray-based model to simulate the effects of sea surface roughness on acoustic wave …

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) …
