- Abstract
Stochastic resonance(SR) is one of the applications in weak signal detection. Many researchers used the combination of the traditional first-order bistable system and genetic algorithm(GA), but the output of first-order bistable system is not smoothly enough, genetic algorithm has the phenomenon of losting in locally value. Aimming at the drawbacks above, second-order and under-damped stochastic resonance based on quantum genetic algorithm(QGA) is proposed. The test in simulation data and vibreation signals show that the presented method can raise the SNR ratio effectively, which has advantages of simplicity and fast convergence speed.
