In-Band Full-Duplex Underwater Acoustic Communication Measurements in a Lake Environment

The presented data contain recordings of underwater acoustic transmissions collected from a field experiment whose goal was to evaluate the feasibility of in-band full-duplex acoustic communications in the underwater environment. The experiment was conducted in Lake Tuscaloosa in June 2021. Two boats, each equipped with an instrument line, were deployed for the experiment. For the local instrument line, the transducer was mounted 6 meters below the water surface. The receiving array was placed 7 meters below the transducer. Eight hydrophones were equally spaced over the 2.8-m receiving array. The remote instrument line shared a similar configuration with the local instrument line, but was with only one hydrophone. Two mutually independent binary phase-shift keying sequences were transmitted simultaneously by the local and remote transmitters at the same frequency band. Two carrier frequencies, 28 kHz and 10 kHz, were used. The receptions were recorded in .wav audio files by the high-precision digital hydrophones. In addition to the acoustic data, a complete set of source information, environmental measurements, and GPS data are included in the data package. Matlab programs are also provided to retrieve the data and facilitate further analysis.

本数据集包含了从一场旨在评估水下环境中带内全双工声通信可行性的现场实验中收集到的水下声波传输记录。该实验于2021年6月在塔斯卡卢萨湖进行。实验中部署了两艘配备测量线的船只。对于本地测量线，换能器被安装在水面下方6米处。接收阵列被放置在换能器下方7米的位置。在2.8米的接收阵列上均匀地分布了八个水听器。远程测量线与本地测量线配置相似，但仅有一个水听器。本地和远程发射器同时以相同频率带宽发送两个相互独立的二元相移键控序列。使用了两个载波频率，分别为28 kHz和10 kHz。接收到的信号通过高精度数字水听器以.wav音频文件的形式进行记录。此外，数据包中还包括了完整的数据源信息、环境测量数据和GPS数据。同时提供了Matlab程序，用于检索数据和促进进一步分析。
