Abstract

fetched live from OpenAlex

An adaptive postdistortion approach that allows for an increase in spectral-efficiency and the portable transmitter power efficiency is presented. The basic idea of the postdistortion technique is to compensate for the adjacent channel's power amplifier AM-AM and AM-FM nonlinearities, at the base station receiver. Coupled with adaption algorithms, the receiver can compensate for slow variations in power amplifier characteristics, where adjacent channel interference is created by power amplifier nonlinearities. Simulation results demonstrate that the postdistortion technique can make an improvement in out-of-band emission by up to 15 dB; the corresponding increase in transmitter power efficiency is approximately a factor of five.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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.
