Bayesian geoacoustic inversion of seabed properties for a continuous-gradient sediment using ship noise in deep water.

This paper presents a Bayesian geoacoustic inversion method for estimating seabed properties using ship noise in deep water. Two bottom-reflected paths are observed in the processing of low-frequency data recorded by a bottom-moored vertical line array. To accurately represent the observed reflection paths and characte...

Multipath-induced non-orthogonal inter-carrier interference mitigation for underwater acoustic orthogonal multicarrier multiple frequency-shift keying with sweep-spread carrier modulationa).

The orthogonal frequency-division multiplexing multiple frequency-shift keying with sweep-spread carrier (OFDM-MFSK-S2C) suffers from inter-carrier interference (ICI), which is often misaligned with the orthogonal subcarrier grid (i.e., the nominal grid). To address this issue, a refined-grid intra-carrier interference...
