The stochastic resonance (SR) phenomenon in high-dimensional nonlinear system and the mechanism of SR are presented in this paper. Based on theoretical analysis, the differences between traditional SR models and the high-dimensional SR model are discussed, and a 5-D SR model is constructed to explain the SR phenomenon in detail. The mechanism of SR is analyzed from the perspective of equilibrium point, and the expression of key parameters is derived. The results of numerical simulation and circuit implementation show that the characteristic of original signal can be well restored whether it is masked by white Gaussian noise or chaotic signal, which shows the great performance of high-dimensional SR system in signal processing. These investigations show the existence of SR in high-dimensional nonlinear system and also can be applied to practical application.
