Analysis of causation of loss of communication with marine autonomous systems: a probability tree approach [PDF]

open access: yes, 2014
The last decade has seen the eagerly anticipated introduction of marine autonomous systems as a pragmatic tool for ocean observation. However, outstanding reliability problems means that these vehicles are not yet fulfilling their true potential.

Prefix-Free Frequency Domain Equalization for Underwater Acoustic Single Carrier Transmissions

open access: yesIEEE Access, 2018
Prefixes, in forms of cyclic-prefixes or zero-padding, have often been viewed as indispensable in underwater acoustic single-carrier transmissions to avoid inter-block interference (IBI) and to formulate circular convolution.
