  • Title: On time delay estimation of epileptic EEG.
    Author: Harris B, Gath I, Rondouin G, Feuerstein C.
    Journal: IEEE Trans Biomed Eng; 1994 Sep; 41(9):820-9. PubMed ID: 7959809.
    Abstract:
    The present study deals with comparative evaluation of various methods for time delay estimations applied to multichannel seizure EEG. The different methods included block algorithms, both in time and frequency domains (such as General Crosscorrelation, FFT, AR), and a new method for time delay estimation based on adaptive least-squares filtering. The various time delay estimators were tested on simulated signals and on real multichannel EEG recorded from rats having generalized seizures with focal onset. The adaptive least-squares filtering (the lattice-ladder type) has been found as the most efficient for time delay estimation.
