Autocorrelation of the signal

We know the spectrum. But how fast does the channel change?

Wiener-Kinchine Theorem

Power density spectrum of a random signal is the Fourier transform of its autocorrelation

Autocorrelation of components

g(t = 0) = local-mean power:

In-phase component and its derivative are independent
