Abstract

At-sea testing of underwater acoustic communication systems requires resources unavailable to the wider research community, and researchers often resort to simplified channel models to test new protocols. The present dataset comprises in-situ hydrophone recordings of communications and channel probing waveforms, featuring an assortment of popular modulation formats. The waveforms were transmitted in three frequency bands (4-8 kHz, 9-14 kHz, and 24-32 kHz) during an overnight experiment in an enclosed fjord environment, and were recorded on two hydrophone receivers. Researchers can use the hydrophone time series to develop and compare advanced signal processing algorithms for wireless digital communications in a real subsea environment.

Instructions:

Unpack TX-waveforms.zip to retrieve the transmit signal waveforms in .wav format, together with symbol values and modulation parameters in .csv format.

Unpack RX-LF.zip to access the hydrophone data (.wav format) with signals received in the 4-8 kHz band.

Unpack RX-MF.zip to access the hydrophone data (.wav format) with signals received in the 9-14 kHz band.

Unpack RX-HF.zip to access the hydrophone data (.wav format) with signals received in the 24-32 kHz band.

Unpack Environmental.zip to access sound speed profiles (.csv format) and a photograph of the sea surface (.jpg format).

See the descriptor article and its supplementary information for a description of the experiment and a detailed specification of the signal modulation formats.
