Towards Robust Multiple Blind Source Localization Using Source Separation and Beamforming
Sensors, 2021 Multiple blind sound source localization is the key technology for a myriad of applications such as robotic navigation and indoor localization. However, existing solutions can only locate a few sound sources simultaneously due to the limitation imposed ...

About Noneigenvector Source Localization Methods
EURASIP Journal on Advances in Signal Processing, 2008 Previous studies dedicated to source localization are based on the spectral matrix algebraic properties. In particular, two noneigenvector methods, namely, propagator and Ermolaev and Gershman (EG) algorithms, exhibit a low computational load.

Free bosons with a localized source [PDF]
Journal of Statistical Mechanics: Theory and Experiment, 2020 Abstract We analyze the time evolution of an open quantum system driven by a localized source of bosons. We consider non-interacting identical bosons that are injected into a single lattice site and perform a continuous time quantum walks on a lattice.
