Abstract

fetched live from OpenAlex

Sa majeste ́ la reine, représentée par le ministre de la Défense nationale, 2002 A set of algorithms has been developed to demodulate and decode the 39 tone signal, which is prevalent in the High Frequency (HF) frequency band. This signal, based on the MIL-STD-188-110A Standard, is one of several different types generated by the AN/PRC-138 Harris radio. Defence R&D Canada (DRDC)- Ottawa has two of these radios. Our work focused on the 39 tone fixed frequency mode, although the 39 tone signal is also the underlying modulation used in the AN/PRC-138’s frequency hopping mode. Thus, the work described here will also be useful to anyone developing dehopping and demodulation algorithms for the AN/PRC-138 frequency hopping signal. The signals were captured by the Agilent Technologies Blackbird system in a laboratory setting. The objective of the task was to gain a detailed understanding of the sophisticated 39 tone signal and to develop software radio algorithms for demodulating and decoding the signal. The report describes the signal structure, the signal capture equipment, and the steps involved in demodulating and decoding the signal so that the

Not 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.
