Abstract

fetched live from OpenAlex

A scheme consisting of a combination of orthogonal transmit diversity (OTD) and OFDM with power allocation is presented. The proposed scheme is a new approach to space-time-frequency coded OFDM (COFDM) that combines OFDM with orthogonal transmit diversity, power control and turbo codes so that the diversity in frequency, time and space is exploited to provide high quality of transmission for wireless communications over frequency selective fading channels with enhanced performance in terms of spectral and power efficiency.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
