具有遍历扩散噪声的随机共振的统计分析

Statistical analysis of stochastic resonance with ergodic diffusion noise

Stefano M. Iacus

摘要:

亚阈值信号通过信道传输,当一些噪声(具有已知结构并与某个电平成比例)添加到数据中时,可以检测到亚阈值信号。存在一个最佳噪声水平,称为随机共振,它对应于信号估计问题中的最高Fisher信息。作为噪声,我们考虑一个遍历扩散过程和渐近被认为是随着时间走向无穷大。我们提出了一致的估计的亚阈值信号,我们进一步解决了假设检验的问题。我们还讨论了随机共振估计和假设检验问题的证据,通过例子。

英文摘要:

A subthreshold signal is transmitted through a channel and may be detected when some noise -- with known structure and proportional to some level -- is added to the data. There is an optimal noise level, called stochastic resonance, that corresponds to the highest Fisher information in the problem of estimation of the signal. As noise we consider an ergodic diffusion process and the asymptotic is considered as time goes to infinity. We propose consistent estimators of the subthreshold signal and we solve further a problem of hypotheses testing. We also discuss evidence of stochastic resonance for both estimation and hypotheses testing problems via examples.
