Abstract

fetched live from OpenAlex

An adaptive resource allocation scheme is designed for OFDM that maximizes the average transmission rate by adapting the power of the data symbols while optimizing the pilot symbol spacing and power. Assuming imperfect channel state information (CSI) at the transmitter, the exact solution obtained for optimum power loading across data subcarriers can not be expressed in terms of elementary functions. A useful approximation, that has the simple form of a water-filling function, is derived for determining the optimum power loading function that is based on imperfect CSI. The merits of the proposed adaptive resource allocation schemes are corroborated by numerical results.

Full frame distilled prediction

Teacher imitation

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.
