Periodic‐phase‐diagram similarity method for weak signal detection
International Journal of Mechanical System Dynamics, 2021 The periodic‐phase‐diagram similarity method is proposed to identify the frequency of weak harmonic signals. The key technology is to find a set of optimal coefficients for Duffing system, which leads to the periodic motion under the influence of weak ...

Fisher-information condition for enhanced signal detection via stochastic resonance [PDF]
, 2011 Various situations where a signal is enhanced by noise through stochastic resonance are now known. This paper contributes to determining general conditions under which improvement by noise can be a priori decided as feasible or not.
