Research on Co-Channel Interference Cancellation for Underwater Acoustic MIMO Communications
Remote Sensing, 2022 Multiple-input–multiple-output (MIMO) communication systems utilize multiple transmitters to send different pieces of information in parallel. This offers a promising way to communicate at a high data rate over bandwidth-limited underwater acoustic ...

Adaptive Underwater Acoustic Communications [PDF]
, 2010 Underwater wireless networks consist of mobile and static nodes, which usually communicate using the acoustic channel since radio transmissions attenuate rapidly and optical communication is only suitable for short distances. The underwater acoustic channel is plagued with issues of high transmission power requirements, rapidly changing channel ...

An efficient scalable scheduling mac protocol for underwater sensor networks [PDF]
, 2018 Underwater Sensor Networks (UWSNs) utilise acoustic waves with comparatively lower loss and longer range than those of electromagnetic waves. However, energy remains a challenging issue in addition to long latency, high bit error rate, and limited ...

Underwater acoustic multiplexing communication by pentamode metasurface [PDF]
Journal of Physics D: Applied Physics, 2021 Abstract As the dominant information carrier in water, the acoustic wave is widely used for underwater detection, communication and imaging. Even though underwater acoustic communication has been greatly improved in the past decades, it still suffers from slow transmission speeds and low information capacity.

Re-Evaluation of RF Electromagnetic Communication in Underwater Sensor Networks [PDF]
, 2010 Most underwater wireless networks use acoustic waves as the transmission medium nowadays, but the chances of getting much more out of acoustic modems are quite remote. Optical links are impractical for many underwater applications.
