Abstract

fetched live from OpenAlex

This paper presents a simplified interpolation equalization technique for filterbank-based DMT systems. In DMT systems, the channel effect in each subchannel can be approximated as a fractional delay, which can be compensated for by using the multitap interpolation equalization technique. By using a large number of polyphase components of the analysis filter output, and using the same polyphase index set for all subchannels, a simplified (suboptimal) interpolation equalization technique is proposed. This technique gives rise to a high transmission bit-rate close to the optimal solution of the interpolation equalization technique. It is also suitable for the timing synchronization.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
