Underwater acoustic communications

Proceedings of Electro/International 1995, 2002
In recent years, underwater acoustic (UWA) communications have received much attention as their applications are beginning to shift from military towards commercial. UWA communications are made difficult by the combined effect of multipath propagation and high temporal and spatial variability of the channel conditions.

Asynchronous multiuser underwater acoustic communications (L)

The Journal of the Acoustical Society of America, 2012
An asynchronous multiuser system is proposed to support multiple-access underwater communications without the use of code-division multiple-access or a feedback channel. The rich multipath channels experienced by spatially separated users will be sufficient to ensure separation of collided packets at the base station. The iterative receiver will employ

Underwater Acoustic Communications Using Time Reversal

IEEE Journal of Oceanic Engineering, 2002
Time reversal, or phase-conjugation, refocuses energy back to a probe source location despite the complexity of the propagation channel. A probe source pulse is transmitted and a complicated multipath signal is measured by an array of source/receiver elements. The signal is time reversed and retransmitted into the ocean.

Bidirectional equalization for underwater acoustic communication

The Journal of the Acoustical Society of America, 2012
The 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 ...

Beyond underwater acoustic communications

OCEANS 2011 IEEE - Spain, 2011
The 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 ...

QoS-enabled underwater acoustic communications

OCEANS 2018 MTS/IEEE Charleston, 2018
For enabling efficient operation of untethered underwater vehicles, error-free underwater communication of command-and-control and telemetry data is a necessity. In contrast, the communication requirements for the sensor data of these vehicles are often less stringent, i.e., a few bad pixels in a SONAR image might be tolerated.

Network-assisted underwater acoustic communications

Proceedings of the Seventh ACM International Conference on Underwater Networks and Systems - WUWNet '12, 2012
For many underwater acoustic applications, the source and receiver systems carry a single transducer antenna. The lack of spatial diversity makes it difficult to carry out phase coherent communications. Using distributed nodes of an underwater acoustic network, this paper address phase coherent underwater acoustic communications using source diversity.
