A Study on channel modeling of underwater acoustic communication
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 1
Abstract
The ability to effectively communicate underwater has numerous applications for researchers, marine commercial operators and defense organizations. As electromagnetic waves cannot propagate over long distances in seawater, acoustics provides the most obvious choice of channel. This research paper carries the study on acoustic channel modeling .In channel modeling, the attenuation due to the wave scattering at the surface and its bottom reflections for different grazing angles and bottom types, ambient noises such as shipping noise, thermal noise, turbulences are considered. Absorption coefficient in the channel with different established models like Thorp’s and Fisher-simmons is also studied.
