Abstract

fetched live from OpenAlex

This paper proposes a flexible low density parity check encoder. This encoder simplifies the calculations found in other flexible encoders by increasing memory usage, allowing for parallelization and faster encoding. The flexibility of this encoder allows it to be used in emerging multi code applications and standards. To evaluate the encoder, a Verilog description was developed and synthesized on an Altera Stratix platform for the IEEE 802.16e WiMAX standard. The implementation used 11,430 logic elements and operated at a maximum clock frequency of 60 MHz. The throughput ranged from 119 Mbps for rate-1/2 codes to 357 Mbps for rate -5/6 codes. A speedup of 2.5-6 times is demonstrated compared to the prior art.

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.
