Raster-scanned wave-digital filter architectures for multi-beam 2D IIR broadband beamforming
Bibliographic record
Abstract
Two-dimensional (2D) beam filters find applications in highly-selective directional enhancement of spatio-temporal (ST) plane-waves (PWs). A 2D raster-scanned (RS) wave-digital filter (WDF) hardware architecture, using a uniform linear array (ULA) of sensors, based on a 2D LR-ladder prototype network is proposed for obtaining M independently-steerable broadband beams having adjustable selectivity. FPGA-based prototypes for 2,3 beams supporting upto 32 broadband sensors are as well as measured results, FPGA resource consumptions, and maximum speeds at various fixed-point precisions, are provided. On-chip verification of the M-beam 2D IIR beam WDF architecture leads to multi-beamforming in applications such as directional audio, multimedia, seismic, and ultrasonic signal processing.

How this classification was reachedexpand
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.
