Low complexity parameter estimation approach for fast time-delay estimation
C. Carlemairn, Stefan Halvarsson, Bo Wahlberg · 2002
Presents algorithms for time-delay estimation based on a parametric approach. The suggested methods combine an exhaustive search with a low complexity since they do not require filtering or correlation computations. Consequently, the problems with local minima of gradient search algorithms are avoided. The proposed detection schemes are experimentally verified by way of computer simulations. Furthermore, receiver operator characteristics are presented.
