Inter-carrier interference mitigation for underwater acoustic communications [PDF]
Communicating at a high data rate through the ocean is challenging. Such communications must be acoustic in order to travel long distances. The underwater acoustic channel has a long delay spread, which makes orthogonal frequency division multiplexing ...

Dam Submergence Flows: An Environmental Flow Prescription Designed to Aid Migratory Fish Passage
River Research and Applications, Volume 42, Issue 1, Page 19-29, January 2026.ABSTRACT As part of a holistic ecosystem‐focused set of unified flow prescriptions, natural spring flood events were enhanced with releases from an upstream reservoir on the Cape Fear River in North Carolina (USA) to submerge a series of low‐use, low‐head lock‐and‐dam structures for anadromous fish to move upstream.

Acceleration‐Aware Estimation and Compensation of Doppler Scale for Mobile UWA OFDM Systems
IET Communications, Volume 20, Issue 1, January/December 2026.We propose a novel method to estimate and compensate for the Doppler scale caused by acceleration in orthogonal frequency division multiplexing (OFDM)‐based underwater acoustic (UWA) systems. Simulation results under additive white Gaussian noise (AWGN), synthetic multipath and realistic waymark channel conditions demonstrate that the proposed approach

Ultrawideband Underwater Acoustic Communication Channels
IEEE Journal of Oceanic Engineering, 2013 Traditional channel models for communications research are designed for narrowband systems. Underwater acoustic communication systems use a bandwidth that is not small compared with the center frequency of the signal and qualify as ultrawideband (UWB) in a relative sense.
