Abstract
In February 2002, the FCC (2002 a, b) issued a ruling that UWB could be used for data communications as well as radar and safety applications. UWB system is constrained to have a maximum power transmission of -41 dB and a bandwidth ranging from 3.1-10.6 GHz. UWB co-exists and does not interfere with existing narrowband or wideband communication systems in the same spectrum. However, due to low transmitting power, UWB is affected by the so-called narrowband interference. This paper presents a method to estimate and detect narrowband signals in radio impulse receiver with the intention of eliminating them. The method uses a power spectral density estimation technique called spectrogram to track down the narrowband signal. The spectrogram at specific frequency range of the active narrowband is larger than its overall average power. A threshold detector is built which reports detection at the frequency range where the narrowband is located. The design correctness has been validated by means of Monte-Carlo simulation using UWB IEEE channel models, time hopping-pulse position modulation technique and Rake receiver

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.
