Experimental verification of an adaptive UWB beamformer based on multidimensional filtering in a real radio channel
Bibliographic record
Abstract
Ultra-wideband (UWB) communication systems can benefit significantly from adaptive wideband beamforming networks, as to have the ability to spatially discriminate some angles of arrival from others could greatly reduce the impact of multipath and co-channel interference. Wideband agile beamforming networks remain a major challenge and are a topic of intense research. State-of-the-art beamforming hardware generally consists of variable delay elements in a delay-and-sum architecture where signals are summed coherently after experiencing a variable true-time-delay (TTD) component. This paper explores a method of achieving UWB beamforming based on multidimensional filtering using sampled signals from a linear antenna array. This beamformer is experimentally characterized in a real UWB radio channel using two techniques.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
