dc.description.abstract | For the optimal performance of underwater acoustic communication, it is important to minimize the effect of the Inter-Symbol Interference due to the delay spread of the multipath channels formed by multiple interactions with the ocean boundaries. The multipath channels have time-varying characteristics due to temporal variations of ocean environments. Especially, the communication channels on moving platforms have high Doppler frequency shifts and low channel coherence times due to spatial environment changes. Recently, acoustic vector sensors have been applied to underwater acoustic communication. A vector sensor can simultaneously measure x, y, and z-components of acoustic vector quantities as well as acoustic pressure with different channel characteristics and signal-to-noise ratios, and therefore, it can be used as a single-input multiple-output communication system. Underwater acoustic communication experiments using an acoustic vector receiver were conducted off the coast of Geoje island in Southeast Korea during the Korea Reverberation Experiment (KOREX-17) in May 2017. In this talk, communication techniques that can give the best performance using acoustic pressure signal and particle velocity signals measured by a single vector sensor in time-varying channel are investigated. © ICA 2022.All rights reserved | - |
