Study on the Application of Weak Signal Recovery System Based on the Stochastic Resonance
Stochastic resonance (SR) enhances the nonlinear system behavior with the assistance of noise. The energy-transfer mechanism makes the weak information revealed in the output spectrum, while the time-waveform is distorted. The factors causing the deviation in the output are presented and the function of the recovery system is proposed. The numerical simulations reveal that the SR recovery method can recover the waveform containing weak information submerged in noise effectively.
