A Natural Language Interface with Relayed Acoustic Communications for Improved Command and Control of AUVs

, 2018
Autonomous underwater vehicles (AUVs) are being tasked with increasingly complex missions. The acoustic communications required for AUVs are, by the nature of the medium, low bandwidth while adverse environmental conditions underwater often mean they are

Robust Interference Cancellation of Chirp and CW Signals for Underwater Acoustics Applications

IEEE Access, 2018
We focus on mitigating strong interferences that can jam underwater acoustics emissions aimed for detection or communications. We consider two types of interferences: narrowband like continuous waveform and wideband like chirp. Both the types are assumed
