Abstract

fetched live from OpenAlex

Digital transmission and recording technologies such as direct broadcasting by satellite and DVD are revolutionizing the home-entertainment consumer electronics industry. It would be economical and convenient to use a single "set-top box" receiver for multiple services. Based on an analysis of the standards for digital audio broadcasting (DAB), digital video broadcasting (DVB) and DVD, a Viterbi decoder and a Reed-Solomon decoder are found to be common channel decoding components that would benefit from co-integration. This paper presents the synthesis-based design and test results of a 62.5 Mbps output rate multi-standard Viterbi decoder implemented in a 0.35 /spl mu/m CMOS process.

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.
