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 ...

Algebraic distributed source localisation algorithm using TDOA and AOA measurements
The Journal of Engineering, 2019 This study proposes an algebraic distributed source localisation algorithm that combines time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed algorithm uses AOAs to remove the unknown parameters in TDOA equations caused

A Hybrid Distance Estimation for Wireless Body Sensor Networks
International Journal of Distributed Sensor Networks, 2013 Wireless body area networks become a new research issue in recent years. In this paper, we propose hibernation and distance estimation schemes for wireless USB (WUSB) over wireless body area networks (WBAN) hierarchical protocol for body sensor networks (

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.
