Question:
Consider a signal x[n] = s[n] + w[n], where s[n] satisfies the difference equation s[n]=0.8s[n-1]+v[n].
v[n] is a zero-mean white-noise sequence with variance ?2v = 0.49 and w[n] is a zero-mean white-noise sequence with variance ?2w = 1. The processes v[n] and w[n] are uncorrelated. Determine the autocorrelation sequences ?ss[m] and ?xx [m].
