Abstract
This letter addresses the problem of on-line sub-sample time delay estimation of narrowband signals of known center frequency. A new form of the Lagrange interpolator filter is presented in this letter, which is incorporated into the explicit time delay estimator (ETDE) method. Simulations show that ETDE with the filter modulated to the signal center frequency significantly outperforms conventional ETDE.Keywords
