How to estimate the parameter of a linear system?

11 November 2016 1 2K Report

We know that the z transform of a system response is of the form:

H(z) =1/( 1-a*z-1 )

How to estimate the coefficient a by using a white Gaussian signal as an input? Thanks.

I got the solution to this questions. Model the all pole system as a auto-regression model. Using least square approach to estimate the parameter a.
