Coherent resonance in a one-way coupled system
We describe the resonancelike behavior of a cooperative phenomenon involving noise, nonlinear systems with intrinsic limit cycle dynamics, and coupling in the absence of an external signal. We show that coupling can significantly sustain the propagation of coherent resonance with considerable enhancement or suppression along a one-way chain. In addition, coherent resonance can occur without tuning for a proper noise level and coupling constant.
