The autocorrelation function of a Markov chain/discrete process is a mathematical tool used to measure the correlation between the current state and the future states of the process. It is a function of the lag between the current state and the future states, and it helps to understand the me...
An Autocorrelation Function is defined as a time domain measure that shows how the correlation between different values of a signal changes as their separation varies. It helps in understanding the memory of a stochastic process without providing information about its frequency content. ...

Eq. (4.3) indicates that taking the autocorrelation of an x(t) function in time domain corresponds to calculating the power spectrum of x(t) in frequency domain. Fig. 4.2 schematically shows the autocorrelation calculation of discrete time series. Corresponding elements of the input series are mu...
It searches periodicity from the sensed binary pattern using a discrete autocorrelation function. Errors that are caused by noise and possible false sensing reports are filtered away from the autocorrelation function. We tested the method with Pare to, Weibull, and exponentially distributed stochastic ...
and a delayed replica of the same signal, expressed by the relation AC = ∫ t 0 s ( t )· s ( t τ) dt , where AC is the autocorrelation, s ( t ) is the signal magnitude as a function of time, t is the time, and s ( t τ) is a replica of t delayed by the time ...
