Abstract
In this paper, we propose a novel peak-to-average power ratio (PAPR) reduction method based on optimum basis function design for wavelet packet modulation schemes. We first establish a cost function to be optimized by analytically deriving an upper bound for the PAPR. The cost function is then used to design the optimum basis function. Simulation results show that the proposed optimum basis function achieves significant PAPR reductions when compared to the conventional Daubechies basis function. In addition, it is also shown that a superior PAPR- bandwidth tradeoff can be achieved through the proposed basis function over the conventional one.

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
