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

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

In underwater acoustic communication, inaccurate synchronization can cause an incorrect
estimation of the uniform Doppler shift and degrade the demodulation performance. In this …

In underwater acoustic communication, nonuniform Doppler shift can severely degrade
demodulation performance. Nonuniform Doppler shift causes nonuniform phase shifts and …

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 …

Underwater acoustic digital communication was investigated by simulation under conditions
of various distortions which seem to degrade communication performance, such as …

The performance of underwater communication system is influenced on channel
characteristic. Delay spread cause by reverberation and multi-path happen the ISI (Inter …
