The Doppler effects is an important reason of the signal distortion generated in the mobile
communication. Especially in the underwater acoustic channel, for the propagation velocity …

Two estimate methods of the Doppler effects in mobile underwater acoustic communication
have been proposed. For the first method the Doppler coefficients are obtained by …

To resolve the low communication rate and susceptible to multipath interference and other
issues of pulse modulation communication method, a new scheme of underwater acoustic …

For obtaining high speed data rate, underwater acoustic communication has several
problems by the different environmental problem compared to wireless communication. To …

It is very important to estimate the signal to noise ratio (SNR) of receive signal accurately
because this parameter will play an important role in the equalization and detection …

Aimed at short propagation distance and poor anti-jamming capability of narrow-band signal
in underwater acoustic (UWA) communication, a new UWA communication scheme is …

Underwater acoustic communication channel is time varying and has Doppler effect due to
wind, sea surface roughness, and platform motion. We have to recognize the changing …

Because of relative motion between transmitter and receiver, the wideband underwater
acoustic multipath channel can be more accurately described by a multi-scale multi-lag …

Underwater scenario with all its complexities has been always very challenging for sonar
signal processing. The reverberation and the fast-fading nature of the channel make it …
