SFI Smart Ocean dataset for underwater acoustic communications

In-situ testing of underwater acoustic communication solutions requires resources unavailable to the wider research community, which often resorts to simplified channel models to test new protocols. The SFI Smart Ocean dataset comprises subsea 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 this dataset to develop and compare advanced signal processing algorithms for wireless digital communications in a subsea environment.水下声学通信解决方案的原位测试所需资源往往为广大科研群体所不具备，因此后者常采用简化信道模型来测试新型通信协议。SFI Smart Ocean数据集包含通信与信道探测波形的水下采集记录，涵盖多种主流调制格式。该数据集的波形于封闭峡湾环境下的一场通宵实验中，在三个频段（4-8 kHz、9-14 kHz及24-32 kHz）下发射，并由两台水听器接收器完成采集记录。科研人员可借助该数据集，开发并对比适用于水下环境无线数字通信的先进信号处理算法。
