Abstract
An embedded pilot signal structure is presented that allows simultaneous processing for time-, and frequency-selective channel variations. The pilot signal is added to an OFDM data signal in the time domain and allows for variable power allocation to the pilot. The structure of the signal shows up as a tone comb in the frequency domain which allows for doppler tracking. It is shown that exact tone interpolation for the data carriers can be achieved as long as the channel's impulse response does not exceed the duration of a period of the pilot signal. Finally, pilots can be allocated in a frequency-division mode to multiple transmitters for MIMO or joint detection applications, avoiding the problem of pilot contamination.

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
