Use the MATLAB randn function to generate 1000 points for x. Generate the output of the unknown system with the ?lter function and b=[1232 1] and a=[1]. Normalise the ?lter output so that its variance is unity, i.e. y = y./sqrt((sum(b.*b)); call the randn function again to generate 1000 points for the measurement noise, scale the values by 0.1 and add them to [ ], and calculate the Signal-to-Noise Ratio (SNR) in dB for y[k] (The power of zero mean white noise is 2 ; when a noise signal is scaled its standard deviation, i.e , gets scaled by the same factor).
- Use the xcorr function to estimate the cross-correlation and autocor relation elements to form Rxx and Pzx.
- Solve for the optimum Wiener ?lter. Is it close to that of the unknown system?
- Repeat the experiment by varying the scaling applied to the additive noise to 1.0 and 10.0, re-calculate the SNR for each case. What is the effect upon the Wiener solution? What happens if w is assumed to be greater than 4?
This assignment is motivated by the use of flybys of planets / moons in spacecraft missions to alter a spacecraft's trajectory (flight path). Planetary flybys can be used to not on

1. Given these sinusoids: x 1 (t) = 0.5cos(25t+20°), x 2 (t)=0.85cos(25t+160°) and x 3 (t)= 0.81cos(25t-145°) (a) Subplot the phasors X 1 , X 2 and X 3 corresponding t
The Efficient Method: Though, in MATLAB, there is another built-in function which specifically produces random integers, i.e. randint. Calling the function with randint (1,1,n
Mathematical operation: For numerical operands, the use of such operators is clear-cut. For illustration, 3 >> 3 ans = 1 >> 9 ans = 0 Though, in the Wo
