Abstract
We propose novel detectors for cooperative spectrum sensing in mixture-Nakagami fading channels, namely 1) the Neyman-Pearson Detector (NPD), 2) a Locally Optimum Detector for weak signals that exploit the correlation between the observations and transmitted signals, 3) a weak signal detector for unknown parameters and 4) two Generalized-Likelihood-Ratio detectors (GLRDs) that exploit the received energies. They significantly outperform energy and cyclostationary detectors in practical scenarios. We also analyze the performance of the NPD and GLRD for unknown transmitted signal over Rayleigh channels, where they reduce to a linear weighted-correlator and a weighted-energy detector respectively.

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 it
