Efficiency of discrimination in some invariant signal transformations
Abstract
The dependence of the discrimination efficiency on the form of invariant ignal transformation is evaluated in terms of the probability of identification error. Discrimination of two classes of signals is considered, after they have been transformed invariantly with respect to amplitude changes and after a delay equal to three instrument readings (decision based on first reading). The error of discrimination is compared with the estimate of the error probability, with functions of two nonstationary characteristics as parameters. These characteristics are expressed through dispersions of adjacent readings.
