Mean frequency estimation of narrowband signals and its application to Doppler ultrasound blood velocity waveform estimation. |
Abstract | ||
|---|---|---|
Many applications involving Doppler signals require the accurate estimation of the power-weighted mean frequency over short durations of the signal due to it's nonstationarity. This paper presents a novel algorithm for estimating mean frequencies using the eigenstructure of the covariance matrix of the Doppler data. Experimental results indicate that this method is superior to the competing non-parametric methods. |
