Application of the Pisarenko Harmonic Decomposition method to physiological data.
In this paper the Pisarenko Harmonic Decomposition (PHD) method is presented as a technique for short duration spectral estimation; it has been tested under various conditions to provide guidelines for its implementation. There appears to be a range of frequencies for which the PHD method gives non-biased frequency estimates. A rapid method for obtaining the sampling frequency required for non-biased frequency estimates is also discussed.
