Abstract

fetched live from OpenAlex

Low-density parity-check convolutional codes combine the good bit error rate performance of low-density parity-check block codes with the ability to encode and decode arbitrary lengths of data. This makes them attractive in applications where the data unit to be encoded varies in length. In this paper we discuss the parallelization of encoders for low-density parity-check convolutional code. We then present results to show how this parallelism impacts on the area and throughput of VLSI implementations of these encoders. We show how this technique can be used to implement encoders with throughputs suitable for next-generation communication standards and other high-speed applications.

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.

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.
