Abstract :
An alternative method for estimating the time delay between two noisy waveforms containing a common signal is presented. The estimate is obtained by means of an approximation to the center of symmetry of a certain correlation function. For narrowband signals preliminary results indicate that the procedure is less sensitive to peak ambiguity which is inherent in the classical optimal estimator.
