Abstract.This paper presents a system parameter estimation method for correlated noise systems by using template functions and conjugate equations. The so-called extended template function estimator is developed on the basis of the conjugate equation theory. Under some weak conditions the parameter estimates obtained with the extended template function method are asymptotically Gaussian distributed. The covariance matrix of this distribution can then be used as a measure of the accuracy. In this paper it will be shown that this matrix can be optimized with respect to the vector of template functions and to the prefilter and that an optimal vector of template functions really do exist.With the optimal choice of the template function vector and of the prefilter, the proposed extended template function estimator reduces to the optimal instrumental variable estimator. When implementing the optimal template function method, a multistep algorithm consisting of four simple steps is proposed to estimate the system parameters and the parameters describing the noise characteristics.Tom tlit.
