On the Estimation of Rational Transfer Functions from Samples of the Power Spectrum
Date of Original Version
A discrete time system with a rational transfer function is identified from real nonuniformly spaced noise-corrupted samples of the power spectrum by solving a set of linear equations using properties of the divided difference operator. Computer simulations show that iterative improvement of the estimates allows the Cramer-Rao (CR) bound to be achieved. © 1993 IEEE
