The correlation between 2 signals/RVs is defined as the expected value between them, given by:, (10) where pxy is the joint PDF between RVs x and y. The autocorrelation (AC) function describes the correlation between a signal’s own samples over time. If the signal statistics do not change over time (i.e. a Gaussian process with a constant ...
