Застосування ефекту стохастичного резонансу для виділення радіосигналів

Abstract

Analysis of radiosignals extraction with the help of stochastic resonance effect are given. As an object of research, linear frequency modulated and phase-code-manipulated signals are considered. The amplitude spectrum of the radiosignal and the process at the output of the stochastic resonator is calculated, the possibility of amplifying the signal and reducing noise at the stochastic resonator output is shown. It has been shown that the stochastic resonance effect provides the standing out of the radiosignal against the background white Gaussian noise.
