摘要: Signal transmission in a nonlinear medium described by one-way coupled bistable systems subject to uncorrelated noise is investigated. It found that can play an active role effectively improve the signal transmission. Stochastic resonance behavior appear process, and at optimal intensity one find largest output amplitude distance. In particular, certain cases undamped be stimulated combined action of both injected noise, while damps exponentially with space distance without noise.
