Blind identification of transfer function model

This paper is concerned with blind identification of a nonminimum phase tra nsfer function model. By over sampling the output at a higher rate than the input, it is shown that its input-output relation can be described by a si ngle input multiple output model (SIMO) with a common denominator polynomia l. Based on the model expression, we present an algorithm to estimate numer ator polynomials and common denominator polynomial in a blind manner. Furth ermore, identifiability of the proposed scheme is clarified, and some numer ical results are given for demonstrating its effectiveness.
