Linear Predictive Coding Pole Processing (LPCPP)

LPCPP is a new parameterised time-frequency method that can observe the dominant frequency change over time.

Linear Predictive Coding Pole Processing (LPCPP) is a parameterised time-frequency method that can be used for identifying and tracking the dominant frequency components change of a signal in real-time (i.e. the term 'real-time' refers to every sampling instant of a discrete signal). The LPCPP method further processes LPC (Linear Predictive Coding) poles to produce a series of reduced-order filter transfer functions to realise the dominant frequency estimation.
