Abstract :
A statistical multidimensional sequence, generated by a non-Gaussian process, passes through a linear space-invariant (perhaps ARMA) model and colored Gaussian noise is added at the output. Given output cumulants, algorithms are derived for the nonparametric reconstruction of the system´s phase as well as for the parametric identification of the ARMA model, which can be noncausal or have nonseparable denominator
