Multi-Source Localization and Data Association for Time-Difference of Arrival Measurements
Gabrielle Flood, Filip Elvander
In this work, we consider the problem of localizing multiple signal sources based on time-difference of arrival (TDOA) measurements. In the blind setting, in which the source signa…
Room Impulse Response Estimation using Optimal Transport: Simulation-Informed Inference
David Sundström, Anton Björkman, Andreas Jakobsson +1
The ability to accurately estimate room impulse responses (RIRs) is integral to many applications of spatial audio processing. Regrettably, estimating the RIR using ambient signals…
Multi-frequency tracking via group-sparse optimal transport
Isabel Haasler, Filip Elvander
In this work, we introduce an optimal transport framework for inferring power distributions over both spatial location and temporal frequency. Recently, it has been shown that opti…
Distributed Adaptive Norm Estimation for Blind System Identification in Wireless Sensor Networks
Matthias Blochberger, Filip Elvander, Randall Ali +4
Distributed signal-processing algorithms in (wireless) sensor networks often aim to decentralize processing tasks to reduce communication cost and computational complexity or avoid…
