Abstract
Ultra wideband (UWB) is considered to be one of the most promising short range wireless communication technologies; due to its high data rate, low cost and low energy consumption. Despite its enviable benefits, the performance of UWB systems may be degraded due to the presence of inband narrow band interference (NBI) signals and this performance must be carefully investigated. To this end; we provide a simple theoretical analysis to the bit error rate performance of the Rake reception of the UWB signal in the presence of NBI signal in the IEEE802.15.3a UWB channel models. The NBI signal is modeled as the standard IEEE802.11a, which is approximated as the sum of “N” tone interferers. We show that our analysis is coincident with the simulation results.

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
