PUMA criterion = MODE criterion
We show that the recently proposed (enhanced) PUMA estimator for array
processing minimizes the same criterion function as the well-established MODE
estimator. (PUMA = principal-singular-vector utilization for modal analysis,
MODE = method of direction estimation.
Multiple source direction of arrival estimation using subspace pseudointensity vectors
The recently proposed subspace pseudointensity method for direction of
arrival estimation is applied in the context of Tasks 1 and 2 of the LOCATA
Challenge using the Eigenmike recordings. Specific implementation details are
described and results reported for the development dataset, for which the
ground truth source directions are available. For both single and multiple
source scenarios, the average absolute error angle is about 9 degrees.Comment: In Proceedings of the LOCATA Challenge Workshop - a satellite event
