ABSTRACT
We study the Stochastic Resonance (SR) in the maximizing network with threshold devices and get results on noise enhancing information transmission. Here the input signals are discrete and the results may be useful for code symbols transmission. With proper thresholds, mutual information between input and output signals increases at first as (additive or multiplicative) noise intensity increases and there is a maximal value when noise intensity reaches the optimum. In addition, larger number of threshold devices leads to better efficacy of SR and the maximum of mutual information goes upwards which means a further enhancement of information transmission. At last, we give the optimal combination of additive and multiplicative noise intensity for the maximal mutual information in the global region. In this case, the efficacy of information transmission is improved the most.
