expected value formula in xcorr
1 view (last 30 days)
when I use the xcorr, the formula used in matlab is C(m) = E[A(n+m)*conj(B(n))] = E[A(n)*conj(B(n-m))] where E is the expected value.
I have seen that matlab does not have a function $expected value", so I was wandering which is the real formula behind xcorr.
Thank you in advance
