Abstract
In this paper, the reassignment method is applied to the local polynomial periodogram to improve the readability of the time-frequency representation. Some interesting properties of the reassigned local polynomial periodogram are demonstrated. Simulations are presented to show that the reassigned local polynomial periodogram can improve the readability of the time-frequency representation, compared to the reassigned spectrogram and reassigned smoothed pseudo Wigner-Ville distribution.
