Abstract: This paper proposes an HB weighted adaptive time delay estimator. The theoretical analysis and the computer simulation show that this new method does not depend on the knowledge about input signals and it has a higher precision and faster convergence speed. Under low SNR conditions, the performances of this method are better than those of LMS TDE obviously. -
