Modeling of Underwater noise

Underwater Acoustic channel is full of various impulsive sources due to which the underwater noise does not follow the standard Gaussian Probability Distribution Function (pdf). This makes the Underwater scenario a little more complicated and leads to performance issues in various fields of underwater applications, e.g. communication, signal processing, and system design, etc. In this paper, we have investigated the underwater noise on real noise data obtained from VENUS via Ocean Canada Network and NOAA for different locations, depths and sampling frequency. Simulation results demonstrate that Generalized Gaussian is the best estimated pdf for the ambient noise.
