On the effect of SNR and superdirective beamforming in speaker diarisation in meetings [PDF]
, 2012 This paper examines the effect of sensor performance on speaker diarisation in meetings and investigates the use of more advanced beamforming techniques, beyond the typically employed delay-sum beamformer, for mitigating the effects of poorer sensor ...

Realization of TDOA estimation architectures [PDF]
Proceedings of 27th Asilomar Conference on Signals, Systems and Computers, 2002 An architecture for the computation of time difference of arrival (TDOA) estimates is proposed. The structure of the various principal components is developed and a complexity analysis is presented. Realization using pipeline FFT and vector processing chips is considered.

Asymptotic Performance of TDOA Estimation Using Satellites
IEEE Transactions on Signal Processing, 2022 We present novel lower bounds on the localization error using a network of satellites randomly deployed on a sphere around Earth. Our new analysis approach characterizes the localization performance by its asymptotic behavior as the number of satellites gets large while assuming a dense network.

TDOA based geolocation using IRLS algorithm [PDF]
2017 International Conference on Intelligent Informatics and Biomedical Sciences (ICIIBMS), 2017 The geolocation method using the wireless signal processing system is widely used in many industrial areas. The time difference of arrival (TDOA) method is one of the most commonly used geolocation methods. The TDOA signal based geolocation system can estimate the position of a mobile object by using at least three base stations in two dimensional ...

Multireference TDOA-based source localization
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2013 Time difference of arrival (TDOA)-based methods usually achieve the most accurate source localization in passive systems. In these methods, one of the sensors is assigned as the reference and the TDOA of the others with respect to the reference is measured. The source location is estimated by processing these TDOAs.
