Published in 2025 at "Journal of Marine Science and Engineering"

DOI: 10.3390/jmse13040675

Abstract: Underwater acoustic signals typically exhibit non-Gaussian, non-stationary, and nonlinear characteristics. When processing real-world underwater acoustic signals, traditional multivariate entropy algorithms often struggle to simultaneously ensure stability and extract cross-channel information. To address these issues, the… read more here.
