Abstract
In a cellular system, low mobility users' transmitted power can be very accurately controlled by a fixed step power control algorithm. This results in lowering the signal to noise ratio necessary to achieve a given frame error rate (FER). However, accurate tracking of multipath fading has the negative effect of increasing the other-cell interference level during periods of deep fades. In this work, we evaluate the capacity of a direct sequence CDMA system (DS/CDMA) assuming low mobility users and taking into account the increase in the other-cell interference due to perfect tracking of multipath fading. The effect of the number of fading resolvable paths on system capacity is determined and the increase in the capacity due to soft handoff is found for different soft handoff thresholds. Finally we investigate the effect of limiting the maximum transmitted power to compensate for multipath fading and find that a limit of 10 dB results in maximizing the system capacity.

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 it
