A Modified Adaptive Stochastic Resonance for Detecting Faint Signal in Sensors

A Modified Adaptive Stochastic Resonance for Detecting Faint Signal in Sensors

In this paper, an approach is presented to detect faint signals with strong noises in sensors by stochastic resonance (SR). We adopt the power spectrum as the evaluation tool of SR, which can be obtained by the fast Fourier transform (FFT). Furthermore, we introduce the adaptive filtering scheme to...
