## Homework Statement

I have a signal where w(n) is white noise

u(n) = .4s(n) +.7s(n-1)-.1s(n-1) +w(n) and where variance of w(n) = .003

I want to find the cross correlation matrix against the optimal delay which I found to be 6.

## Homework Equations

## The Attempt at a Solution

E[U(n)d*(n-6)] where U(n) =column vector [u(n),u(n-1),….u(n-8)]

I can't for the life of me understand what how to get the cross correlation vector p. Could someone explain how to obtain it? I can not even find examples online. Everything seems to abstract.
