Abstract
A new iterative algorithm for variable time delay estimation (TDE) is presented. The algorithm is based on a system model where two received signals of the form r < inf> 1 (i) = s(i)+n < inf> 1 (i) r < inf> 2 (i) = s(i-D(i)) + n < inf> 2 (i) are used to estimate the delay. In the model i is the discrete-time index, s(i) is the source signal, D(i) is the (integer) delay waveform, and n < inf> 1 (i) and n < inf> 2 (i) < sup> are colored and correlated noises. Based on the minimum mean-squared error criterion and a linearized observation model, we devise an iterative delay estimator. The estimator involves a weighting function that is designated to facilitate the convergence to delay estimate. Simulations are run to test the performance of the algorithm. Results of the simulations are presented. © 1992 IEEE.
