Optical-Based Underwater Communications
Optical Fiber Communication Conference, 2018A high-speed 24 Gb/s PAM4 optical-based underwater communication (OBUC) with afocal scheme for reducing/expanding collimated beam diameter is demonstrated. Such proposed OBUC link is better than existing OBUC given its practicability for high-speed underwater link.

Bidirectional equalization for underwater acoustic communication
The Journal of the Acoustical Society of America, 2012The bidirectional decision feedback equalizer (BiDFE) that combines the outputs of a conventional decision feedback equalizer (DFE) and backward DFE can improve the performance of the conventional DFE by up to 1–2 dB based on simulations. In this letter, the BiDFE concept is extended to multichannel time reversal communications involving a DFE as a ...

Real time underwater communications
Proceedings of OCEANS'94, 2002Achieving reliable high speed digital communications over an underwater channel is a challenge that many scientists are trying to take up. For various applications such as remote control and data exchange, for example between an autonomous underwater vehicle and a surface vessel, the need is getting more and more important in designing reliable ...

Beyond underwater acoustic communications
OCEANS 2011 IEEE - Spain, 2011The ability to communicate underwater using acoustic energy in place of electromagnetic energy is rapidly becoming commonplace. Indeed, vendors and academic researchers in many advanced countries are pursuing the development of acoustic modems. The emphasis often varies among these efforts: some, especially academic researchers, focus on increased ...

Long distance underwater communication
The Journal of the Acoustical Society of America, 19811. A transmitter for use in long distance underwater communication comprig: (a) an electrostrictive transducer operable for radiating at least one hundred kilowatts of acoustic power into sea water in a frequency band fifty to one hundred cycles wide about a median frequency below five hundred cycles per second, (b) an alternating current ...
