We describe the resonancelike behavior of a cooperative phenomenon involvin
g noise, nonlinear systems with intrinsic limit cycle dynamics, and couplin
g in the absence of an external signal. We show that coupling can significa
ntly sustain the propagation of coherent resonance with considerable enhanc
ement or suppression along a one-way chain. In addition, coherent resonance
can occur without tuning for a proper noise level and coupling constant.
