autocorrelation

A measure of how closely a signal in a time series resembles a time-delayed image of itself—periodic signals are highly autocorrelated; random signals are not.

The level of autocorrelation in the data (high [rho] values, which lower the effective n) tends to increase as the time interval becomes smaller.

The technique that is proposed in this paper based on band-pass filtering of the original time domain signal using a band pass filter that centers on the region of high frequency energy, and demodulate the filtered signal by getting Envelope and Autocorrelation enhancement.
