DescriptionAcoustic waves propagating through shallow underwater acoustic channels experience Doppler shift, multipath, and other impairments seen in other wireless channels. In shallow underwater acoustic channels, Doppler shift and channel reverberation are severe problems and generally need to be compensated.
In Nov. 2009, ARL engineers deployed a mobile single-element transmitter and a stationary five-element receiver in Lake Travis in Austin, Texas, and took about 90 minutes of field measurements. The resulting Nov. 2009 Five Element Acoustic Underwater Dataset consists of 360 packet transmission samples, with each packet having about 0.5 s in length. The experiment operated in shallow lake water (37m in depth) over short distances (15-1269 m). Many different single-carrier transmission waveforms were sent.
The dataset is stored as Matlab data files (.mat files), which consist of a Matlab structure and a Matlab matrix of data. Each Matlab data file in the dataset can be loaded in Matlab using the load command. Alternatives for reading the datasets include freely distributable Octave and open source MATIO. We've tested reading and processing the data sets using Octave 3.2.4. More information about the datasets is available in the Introductory Document below.
The dataset was collected to support efforts in modeling wireless underwater acoustic channels and in evaluating receiver designs. We have used the dataset to evaluate Doppler correction techniques.
