Four methods of identification of nonminimum phase systems with finite impulse response are compared in this project. Zeros move-close to the unit circle with one located inside it and the other one located outside it.
Additive noise is Gaussian, white or colored.
Signals are non-Gaussian distributed. The simulation study suggests that estimation of the IT coefficients, the bicepstrum method is the preferred method. Both MU and RG methods are stable at estimating the phase of IR coefficients, but poor at estimating the magnitude.
