Robustness of the reference symbol assisted multistage successive interference cancelling receiver with imperfect parameter estimates
Bibliographic record
Abstract
This paper investigates the sensitivity to system imperfections of a multistage successive interference cancelling receiver with reference symbol assisted channel estimation. In particular, performance losses due to nonideal transmitter power amplifier gating, imperfect power control and synchronization errors in the RAKE receiver are determined. The results show that for path loss exponent of 4. Imperfect amplifier gating causes a relatively minor decrease in the system capacity while no such effect is observed for path loss exponents of 2 and 3. As expected, relaxing of power control has a similar capacity reducing effect. In spite of these two effects the resultant capacity is still significantly higher than that with the conventional matched filter receiver. Chip synchronization errors of the order to be expected in a properly designed CDMA system also have only minimal influence on performance. Therefore, conventional synchronization algorithms should perform adequately with successive interference cancelling receivers considered in the paper.

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.
