Enhanced information transmission with generalized Gaussian signal via suprathreshold stochastic resonance

We investigate the noise-enhanced information transmission with generalized Gaussian signal via the measure of mutual information, in context of suprathreshold stochastic resonance (SSR). The effects of the noise intensity and the exponent parameter of the input signal on mutual information are discussed. It is shown that the qualitative behavior of SSR does not depend on the actual signal and noise distribution. However, it is found that the exponent parameter of the generalized Gaussian signal distribution has a crucial effect on the position or the maximum value of the mutual information.
