Performance of 2-bit power control algorithm in CDMA networks under Rayleigh fading: a comparative simulation study
Bibliographic record
Abstract
Transmit power control (TPC) comprises techniques and algorithms used to manage the transmitted power of base stations and handsets. TPC not only helps minimize the expensed battery power but also decrease the interference power to other users. In WCDMA standards, TPC command rate is 1500 Hz. A command is issue to either increase or decrease the transmit power by 1 dB using a single bit. In this paper, we investigate a 2-bit TPC algorithm that increases/decreases transmit power of the mobile by either 1 dB or 2 dB. The performances of the 2-bit and 1-bit TPC algorithms are compared by computer simulation in Rayleigh fading environment. We demonstrate that 2-bit TPC algorithm provides the necessary compensation of channel loss in multipath fading. As a result, 2-bit algorithm operates with lower battery power than that of 1-bit algorithm for the required service quality.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
