Abstract

fetched live from OpenAlex

A study for the adjacent channel power ratio (ACPR) for modified linear amplification using nonlinear component (LINC) power amplifiers used in wireless communication systems when branch signals are digitally baseband filtered is proposed. The LINC is modified by sending the filtered branch signals and then combine them at the receiver. The IEEE802.11g standard, which operates at 2.4 GHz, employing the OFDM signals is used to show the system performance compatibility with the standard and efficiency improvements. Results show that the ACPR is lowered when using a least square filter, from -26.1dBc to -63.8dBc. The efficiency is improved by 3.4 times when compared with that of a regular LINC.

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.
