Antenna-array 2D-IIR digital filters for carrier-modulated frequency-agile and cognitive wireless systems
Bibliographic record
Abstract
The application of a 2D IIR digital filter, having a broadband beam-shaped 2D passband, is investigated for beamforming in narrowband wireless communication systems. Specifically, their use for interference rejection in a carrier-modulated communication system is proposed. Monte-Carlo simulations of the bit-error-rate, as a function of the antenna-side signal-to-interference ratio for a 1 GHz BPSK-modulated source operating at 25 Mbps over a 32 element array, confirm a signal-to-noise-plus-interference ratio (SINR) system gain of 10 to 15 dB relative to the non-beamformed case. The proposed method allows a single broadband beamformer to operate over a wide frequency bandwidth containing multiple frequency-agile channels. This particular application is potentially well-suited for cognition-enabled base stations.

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.
