A new Algorithm for Explicit Adaptation of Time Delay

By using an adaptive technique similar to the one developed by Etter and Stearns [1], a novel constrained algorithm for explicit time delay estimation (TDE) is derived. The adaptive process provides an unbiased delay estimate and its respective performance surface, learning characteristics and delay variance will be given. The mean-square error surface, though a function of the estimated delay only, is multimodal and proper initialization is required to guarantee global convergence. Simulation results are included to validate the convergence behavior of the TDE system. © 1994 IEEE
