Contributed Review: Source-localization algorithms and applications using time of arrival and time difference of arrival measurements.

Review of Scientific Instruments, 2016
Locating the position of fixed or mobile sources (i.e., transmitters) based on measurements obtained from sensors (i.e., receivers) is an important research area that is attracting much interest.

TDOA--based localization in two dimensions: the bifurcation curve

, 2014
In this paper, we complete the study of the geometry of the TDOA map that encodes the noiseless model for the localization of a source from the range differences between three receivers in a plane, by computing the Cartesian equation of the bifurcation ...

Time difference of arrival (TDOA) estimation using wavelet based denoising

, 1999
The localization of mobile wireless communication units is studied. The most important method of localization is the time difference of arrival (TDOA) method. The wavelet transform is used to increase the accuracy of TDOA estimation. Several denoising techniques based on the wavelet transform are presented in this thesis.
