Abstract

A new time-delay estimation method based on the combination of wavelet transform and cross-correlation is proposed. This method uses compromise threshold function and Birge-Massart threshold selection strategy to denoise signals, and then determines the time-delay between the signals by computing the cross-correlation of the denoise signals. Comparative study of the new method, cross-correlation method and second correlation method were carried out. Results show that these three methods can give good time-delay estimations when the SNR is not low; however, only the new method can give good time-delay estimations if the SNR is very low and the noises are strongly correlated.
