surrogate data, information criterion, signal-to-noise ratio, Gaussian noiseAbstract
The problem of enhancing the estimation efficiency of the number of harmonic components of signal based on its observation in the presence of additive white Gaussian noise using the surrogate data technology has been considered. The results of simulation modeling are presented. The application of this technology was shown to be effective at small and large values of the signal-to-noise ratio (SNR), when the frequencies of signal components were a multiple of the observation sampling frequency in the frequency domain.
