Abstract

While the LMSTDE interpolates filter coefficients to determine the time difference of a signal received at two separated sensors, the ETDE adapts and tracks the time delay explicitly. In this paper, the convergence dynamics of these two approaches are analyzed when the delay is a linearly time-varying function due to relative motion between the signal source and the receivers. The merits of these methods in terms of parameter estimation and computational load will be discussed. Simulation results show that ETDE outperforms LMSTDE for delay and Doppler estimation and its performance is comparable to the CRLB under noisy environment.
