There are many reports on extracting the singlefrequency signal under noise by the stochastic resonance, but in which the information that the signal carries is zero.
已有利用随机共振在强噪声下提取单一频率信号的若干报道，但单一频率信号所携带的信息量为零。

Simulation shows the algorithm has good results in case of estimating singlefrequency, multiple frequencies and changing frequency under different SNR, and has robustness for noise inference.
A single carrier modulation scheme suitable for use in high frequency communication systems is provided that achieves improved residual frequency error and phase noise estimation.
