Abstract
The transmission of weak noisy signal by parallel array of dynamical saturating
nonlinearities with secondorder is studied. Firstly, the numerical results
demonstrate that the output SNR can be enhanced by parallel array of dynamical
saturating nonlinearities with second-order by tuning the internal noise.
Secondly, the SR effects can be optimized by the self-coupling coefficient
of the dynamical nonlinearity. Then, the SR effects when the non-Gaussian
noise acts as the external noise are superior to that with external Gaussian
noise.
