NSF Project: In Band Full Duplex Underwater Acoustic Networks
Synopsis

Research Methodology
The major hurdle to achieve underwater acoustic IBFD communications is the presence of strong acoustic self-interference. Therefore, the challenge is how to achieve adequate suppression of the self-interference in the dynamic ocean environment. We take an experiment-based approach in research. A series of field experiments have been conducted in an indoor tank, local rivers, and a large lake. The main objective of these experiments is to collect self-interference measurements at different acoustic frequencies, different transmitter-receiver geometries, different transmitter orientations, etc. Different physical isolation methods have been tested. Based on these field measurements, we analyze the characteristics of the self-interference channel and develop effective signal processing methods for underwater acoustic IBFD receivers.

Link to Data Repositories
We are striving to share experimental data and processing tools to the research community. Segments of acoustic IBFD measurements have been organized and are ready for sharing, see the user guide below of our shared data from our 2019 lake experiment. Please visit to IEEE Dataport to retreive the shared dataset: https://ieee-dataport.org/open-access/band-full-duplex-underwater-acoustic-communication-measurements-self-interference.
