In order to deal with the frequently encountered non-stationary random signals in signal processing,they can be divided into sub-stationary random signals,and autocorrelation function can be used to reflect the essential characteristics of sub-stationary signals.The computation of piecewise stationary stochastic process autocorrelation function was discussed.In order to reduce the amount of

Stationary process autocorrelation

Definition: The autocorrelation function (acf) of a stationary time series is the function whose value at lag $h$ is: $$ \rho(h) = \frac{\g(h)}{\g(0)} = \Corr(X_t, X_{t+h}) $$ By basic properties of the correlation, $−1 \leq \r(h) \leq 1$ for all $h$.

Example 3 (Process with linear trend): Let t ∼ iid(0,σ2) and X t = δt+ t. Then E(X t) = δt, which depends on t, therefore a process with linear trend is not stationary. Among stationary processes, there is simple type of process that is widely used in constructing more complicated processes. Example 4 (White noise): The The stationary Markov process is considered and its circular autocorrelation function is investigated. More specifically, the transition density of the stationary Markov circular process is defined by two circular distributions, and we elucidate the structure of the circular autocorrelation when one of these distributions is uniform and the other is arbitrary.
