3. This pertains to the noise cancellation problem. Let x(n) = d(n) + g(n) d(n) = sin(nw, +0), where d(n) is the desired signal, it is a sinusoid of frequency w = 0.051 with a random phase uniformly distributed between -n ton. Given a noise process v2(n), which is correlated with g(n), is measured by a secondary sensor, design a Wiener filter to estimate d(n). v2(n) = 0.8v2(n − 1) + g(n) where g(n) is unit variance white noise process. Generate 500 samples of each of these processes. Obtain the coefficients of the Wiener filter for filters of order p = 2,4, and 6. Make plots of the estimated process ĝ(n) and compare the average squared errors for each filter.
