Abstract
In this paper, we compare the effects of multi-band orthogonal frequency-division multiplexing (MB-OFDM) and direct-sequence ultra-wideband (DS-UWB) interference on a narrowband (NB) signal. For this purpose, we first derive an analytical expression for the moment generating function (MGF) of DS-UWB interference. Based on this result we obtain an expression for the bit error rate (BER) of a binary phase-shift keying (BPSK) NB signal impaired by DS-UWB and additive white Gaussian noise which lends itself to efficient numerical evaluation. We show that for NB signal bandwidths much smaller than the DS-UWB bandwidth the NB system performance strongly depends on the carrier frequency offset between the NB signal and the DS-UWB signal and we derive corresponding BER approximations. Finally, we show that whether MB-OFDM or DS-UWB interference leads to less performance degradation strongly depends on the NB signal bandwidth

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.
