摘要：
At the University of Pardubice there is currently developed a modern positioning system for localization of fire brigade and members of rescue corps. The TDOA based system use an OFDM wideband signal to separate direct propagated signal from mixture of its replicas created in a multipath channel. In the paper, the model of a received signal is presented and this signal is processed by spectrum analysis methods to estimate the direct propagated signal delay. The accuracy of nonparametric, parametric and subspace methods is compared and new insights into application of spectral analysis methods are presented.
