Acoustic RIS for Massive Spatial Multiplexing: Unleashing Degrees of Freedom and Capacity in Underwater Communications
Longfei Zhao, Jingbo Tan, Jintao Wang +2
Underwater acoustic (UWA) communications are essential for high-speed marine data transmission but remain severely constrained by limited bandwidth, significant propagation loss, a…
On the Characterization and Evaluation of Doppler Squint in Wideband ODDM Systems
Xuehan Wang, Jinhong Yuan, Jintao Wang +1
The recently proposed orthogonal delay-Doppler division multiplexing (ODDM) modulation has been demonstrated to enjoy excellent reliability over doubly-dispersive channels. However…
Data-Driven Modulation Optimization with LMMSE Equalization for Reliability Enhancement in Underwater Acoustic Communications
Xuehan Wang, Hengyu Zhang, Jintao Wang +2
Ultra-reliable underwater acoustic (UWA) communications serve as one of the key enabling technologies for future space-air-ground-underwater integrated networks. However, the relia…
Covering Underwater Shadow Zones using Acoustic Reconfigurable Intelligent Surfaces
Longfei Zhao, Jingbo Tan, Jintao Wang +2
To better explore the oceans, seamless communication coverage of the vast 3D underwater space is desired. Unlike terrestrial networks using radio signals, underwater acoustic commu…
