Abstract
In this paper, we propose a novel algorithm to reduce the out-of-band radiation for the Discrete Fourier Transform (DFT)-based orthogonal frequency division multiplexing (OFDM) cognitive radio (CR) systems. Further, we provide a performance comparison for the proposed and conventional algorithms in terms of power spectral density (PSD), peak to average power ratio (PAPR), and required bandwidth for overhead. Simulation results demonstrate that the proposed algorithm outperforms the conventional algorithms at the cost of an overhead, with a similar PAPR. The trade-off between the PSD (as a benefit) and the PAPR and overhead (as costs) is emphasized, being used for the selection of specific algorithm parameters.

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
