Abstract

An adaptive configuration is introduced for time delay estimation whereby two adaptive filters, one giving a time delay and another a time advance of equal amount, are adapted simultaneously to minimize the errors. This configuration gives a fourfold increase in convergence speed compared with the conventional single adaptive filter. Proofs for convergence and speed up are given, together with verification from simulation results
