Evaluation of bistable array in non-Gaussian noise for signal transmission
In the field of nonlinear signal processing,the enhancement of the output-input signal-to-noise ratio gain via the array stochastic resonance mechanism becomes a hot topic.This paper evaluates the transmission performance of the bistable parallel array in non-Gaussian noise.It is found that,via the array stochastic resonance effect,the system output signal-to-noise ratio can be further improved.For an appropriate array size and in certain region of internal noise intensity,the output-input signal-to-noise ratio gain is proved to be beyond unity.When the noise levels are fixed,it is observed that the possibility of signal-to-noise ratio gain exceeding unity also exists for the subthreshold signal as the array size increases.
