A Novel Dynamic Stepsize Power Control Algorithm for UMTS W-CDMA Systems
Bibliographic record
Abstract
Power control is an essential mechanism for wideband code division multiple access (W-CDMA) systems. In our earlier work, a combined power control and a greedy rate packing (GRP) allocation scheme employing conventional fixed stepsize power control (FSPC) is discussed and evaluated. In this paper, we extend the algorithm to apply a novel dynamic stepsize power control (DSPC) algorithm to improve system performance. The dynamic stepsize (DS) is determined by the difference between the target SIR* and the received SIR. A larger stepsize is applied when the difference between the received SIR and the target SIR* is large to enhance tracking ability, and vice versa to reduce granular noise. Simulation results show the effectiveness of the proposed DSPC algorithm, with around 2% gain of throughput, 6.5% average power consumption saving and 0.5 dB standard deviation (STD) reduction of the received SIR, when compared with the FSPC scheme

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
