Estimation of polyharmonic signal parameters

Estimation of polyharmonic signal parameters

A new algorithm was proposed to estimate all parameters of the polyharmonic signal such as frequencies, amplitudes, phases, and shifts. Exponential convergence to zero of the errors of estimating the desired parameters was shown. The algorithm features noise-immunity to additive noise in the measure...

Zusammenfassung:A new algorithm was proposed to estimate all parameters of the polyharmonic signal such as frequencies, amplitudes, phases, and shifts. Exponential convergence to zero of the errors of estimating the desired parameters was shown. The algorithm features noise-immunity to additive noise in the measurement channel. The dynamic dimensionality of the estimation algorithm is 3 k , where k is the number of harmonics
