This dissertation aims to describe all the research work performed to study binary digital
modulations in the aquatic environment using acoustic waves. The underwater environment …

A non-linear acoustic wave propagation model has been developed to determine the effects
of ocean variations in the acoustic field, and to determine the signal measured by a receiver …

A wireless underwater acoustic communication algorithm based on the combination of chirp
modulation and direct-sequence spread-spectrum signalling is presented. In this paper, the …

Underwater acoustic (UWA) channel is characterized as a severe multipath propagation
channel due to signal reflections from the surface and bottom of the sea, that is affected by a …

This paper is focused on the characteristics of underwater acoustic communication channels
and their implications on the design of bandwidth efficient modulation and demodulation …

Traditional channel models for communications research are designed for narrowband
systems. Underwater acoustic communication systems use a bandwidth that is not small …
