Abstract
The frequency-hopping orthogonal frequency-division multiplexing (OFDM) proposal, known as multiband OFDM, is a strong contender for the physical layer IEEE standard for high-rate wireless personal area networks (WPANs) bused on ultra-wideband (UWB) transmission. In this paper we analyze the performance of the multiband OFDM proposal. To this end, we (a) study the channel model developed under IEEE 802.15 for UWB radio from a frequency-domain perspective suited for OFDM transmission, (b) develop and quantify the appropriate information-theoretic performance measures, (c) compare these measures with simulation results for multiband OFDM systems, and (d) consider the influence of practical, imperfect channel estimation on the performance.

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
