Estimation of signal-to-noise ratio in signals contaminated by white noise


Abstract:

A method is proposed to estimate the SNR of a signal with the assumption that noise is white and zero-mean. This method is based on a time delay that calculates the normalized integrals of the squared signals. The behavior of this estimate is biased with a bias that is a function of the SNR. This property is used to estimate SNR. This result can be applied to any signal, even if it is not repetitive. The SNR information obtained can be used to analyze the signal quality or to find the limits of subsequent signal processing, as in case of signal averaging.
