Time delay estimation using the adaptive delay element
Abstract
The estimation of time delay between two narrowband signals is a common problem in applications such as seismic and acoustical signal processing. A simple real-time adaptive delay element is used to compare delay estimation accuracy for both stationary and nonstationary time delays as well as for varying input signal-to-noise ratios. The comparison includes a modification to the adaptive algorithm which yields a smoothed delay estimate.
