Abstract

Underwater acoustic communication systems are prone to performance degradation caused by the impulsive noise generated by snapping shrimps. In mathematical analysis or simulations, this noise is commonly modeled via temporally uncorrelated samples following the symmetric alpha-stable (SαS) distribution. In this article, the adequacy of this distribution is analyzed in contrast to the alpha-sub-Gaussian (αSG) distribution with non-zero temporal correlation, in the context of underwater spectrum sensing.
