Write by matlab program code to do following by (wiener filtering):

1- generate noise. t will have gausian distrubtion normal distribution with variane of 0.5.

V=0.5 randn(1,500)

2- generate a desired signal as cosine function d=cos(0.1n).

3-noisy signal. x=d+v

4- generate auto correlation matrix having order of 10 by 10. RT (xcorr)

5- obtain cross correlation in vector Pdx. (xcorr)

6- obtain optimum wiener filter coefficients. w= R^-1 *Pdx.

7- compute output of winear filter. caps_d=filter(w,1, x)

8- computer error e[n]=d[n]-cups-d.
