Recently, much research has been conducted in the field of identification of the linear models. In general, these methods use a time-domain estimate or a frequency-domain estimate. In this paper, the time-domain estimate and the frequency-domain estimate were combined to identify the autoregressive exogenous noise (ARX) interference model. The concept of a general prediction error criterion is introduced for the time-domain estimate. An optimal frequency estimation is introduced for the frequency-domain estimate. A new identification method, called the empirical frequency-domain optimal parameter estimate, is proposed for disturbed systems. It is fully applied and developed for the output error model and a specific case or the ARX model. The algorithm theoretically provides the globally optimum frequency-domain estimate of the model. Some simulations are included to illustrate the new identification method.
