Question:
Using the MATLAB function awgn, repeat the recursive least-squares estimation of Example 10.4 when the output is corrupted by a white Gaussian noise with 10.0 dB SNR. Compare the estimation results with those for 1.0 dB SNR.
Example 10.4
Consider the input and output data of a LTI system with sampling time T = 0.1 s:
We wish to generate the least-squares estimate of the transfer function from the given input–output data. For this one may write a simple MATLAB code using the function arx as follows.
