Ultra wideband indoor channel measurements using a wideband plate monopole antenna
Bibliographic record
Abstract
A Vector Network Analyzer (VNA) was used to determine the ultra wideband (UWB) indoor propagation channel capacity and mean and standard deviation of the RMS delay spread. A wideband plate monopole antenna was designed and tested to work as a receiver over the frequency band 2.4–3.9 GHz. The standard 1–12 GHz horn was used as the transmitter antenna. The channel capacity was calculated and plotted against signal to noise ratio (S/N). The UWB channel transfer function was also measured. The output of the measurements was in the form of power delay profile (PDP) of the channel and the output of the data processing was the mean and standard deviation of root-mean-square (RMS) delay spread. Both mean and standard deviation values are increased with the increase of transmitter-receiver separation for the non line of site (NLOS) scenarios.

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.
