description: The aim of this research is to investigate the applicability of the MUSIC method for demodulating signals in multimode fiber-optic interferometers. The outcome of this final qualification work involved studying the influence of errors in the specified number of signal components in the MUSIC method on the accuracy of frequency estimation of harmonic components, the impact of additive noise on the accuracy of parameter estimation of harmonic components, and the effect of parasitic frequency modulation on the accuracy of parameter estimation of harmonic components. Conclusions have been drawn indicating that the error magnitude is smaller when underestimating the number of components for MUSIC. The level of additive noise affects the overall error for signals with a small number of useful components. A high level of parasitic frequency modulation significantly increases the magnitude of the overall error. These findings have been experimentally validated. The results of this final qualification work provide new insights into the parameters of the MUSIC method and can be applied in signal processing for multimode fiber-optic interferometers and other fiber-optic sensors.
