Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The correlation matching property of all-pole models does not extend readily to pole-zero models. It is proved that, if the number of poles in a pole-zero model is strictly less than the number of given correlations, a pole-zero model that matches the given correlations may not exist, irrespective of the number of zeros in the model. It is also shown that if one adds a set of cepstral constraints, a maximum-entropy pole-zero model that matches the correlation and cepstral constraints may not exist. It is concluded that pole-zero modeling minimizing some error criterion might be preferable to exact constraint matching. >
