Abstract

 Detection and estimation under poor signal-to-noise (SNR) conditions may require the averaging of an ensemble of time-locked signals. However, when there is a vacation in signal delay, It is necessary to adjust the alignment of the different signals in the ensemble in order for averaging to produce an undistorted estimate of the signal waveform. Two techniques for alignment are considered; the fiducial paint alignment and the template updating technique. The two techniques are applied to simulated and true ECG signals. It is shown that the morphology of the estimated averaged waveform using the fiducial point alignment is affected by the SNR and that the template updating technique is more convenient for such a purpose.
