Underwater acoustic (UWA) communication is an essential technology that supports
underwater surveys by transmitting images and movies wirelessly. However, UWA …

Mobile underwater acoustic (UWA) communication is still challenging, since the mobile
UWA channel is characterized by severe delay and Doppler spreads. In this paper, we …

Underwater acoustic (UWA) channels are one of the historical mobile ultrawideband
channels characterized by large delay and Doppler spreads, but reliable UWA …

Underwater acoustic (UWA) communication in shallow water has been challenging owing to
multipath-induced signal distortion and motion-induced Doppler distortion. In this study, we …

In this study, we apply Doppler shift correction schemes for underwater acoustic (UWA)
communication with orthogonal signal division multiplexing (OSDM) to achieve stable …

Underwater acoustic (UWA) channels are characterized by a severe spread in time and
frequency, and are usually labeled as “doubly spread channels.” In this paper, we propose …

Underwater acoustic (UWA) communication is still a challenging area of research, as
methods to deal with large intersymbol interference and Doppler spread are needed. We …

In this paper, we propose a novel underwater acoustic (UWA) communication scheme that
achieves energy and spectrum efficiency simultaneously by combining Doppler-resilient …

Underwater acoustic (UWA) communication is an ongoing challenge because of the heavy
time spread by multipath and Doppler spreads. In this paper, we propose a UWA …

This paper is about the underwater acoustic (UWA) communication using orthogonal signal
division multiplexing (OSDM) in shallow water, whose environment is time spread and …
