Fengjuan Li, Yao Shi · Journal of Changchun University · 2004
Among numerous high resolution estimations,the cross-spectral estimation methods are efficient in estimating the parameters of signals embedded in the colored noise.This paper introduces the weighed cross-spectral estimation method based on the ESPRIT to estimate the frequency of the Sinusoid.This method overcomes the searching procedure inherent in all the previous cross-spectral estimation and the limitation of auto-spectral estimation methods for noise(require noise to be white and gauss).This method applies in the modern cross-spectral measurement instrument.Simulation shows that the method enhances the performance of spectral estimation without the pseudo peak.
