摘要：
This paper Investigates four methods to estimate the amplitude of a sinusold buried in noise, using the phenomenon of stochastic resonance (SR) to obtain the best estimate. SR is a cooperative effect in which the power in the broadband part of the spectrum is fed in to the output power of the signal frequency. We use a 3-level quantizer In our experiments to quantize the sinsoid buried In noise after variance-controlled AWGN is added to It. We estimate the amplitude at the optimum variance; which is obtained from the experimentally obtained SNR data.
