Abstract: Abstract Orthogonal time-frequency-space (OTFS) is a new two-dimensional (2D) modulation technique that offers reliable communications over time-varying channels. Due to the characteristics of underwater acoustic (UWA) channels, the computational complexity of traditional OTFS receivers is… read more here.

DOI: 10.3390/jmse13061082
Abstract: A passive time reversal method with a metamodel (PTR-MM) is proposed to improve underwater source localization under ocean conditions. PTR-MM eliminates model mismatch errors by replacing the conventional sound propagation model with a Kriging metamodel.… read more here.
