Modeling and analysis of TCP performance under joint rate and power adaptation in multi-cell multi-rate WCDMA systems
Bibliographic record
Abstract
This paper models and analyzes the performance of TCP (transmission control protocol) under joint rate and power adaptation with constrained BER (bit error rate) requirements for downlink data transmission in a multi-cell VSF (variable spreading factor) WCDMA system. The performance of TCP in a wide area Internet environment is evaluated by using computer simulation considering both random user mobility with uncorrelated shadowing and directional user mobility with correlated shadowing. Since the short-term fading (i.e., multipath fading) changes more rapidly compared to long-term fading (i.e., shadowing), multipath fading is assumed to be independent over successive adaptation intervals. System dynamics under multiple concurrent TCP connections is simulated for both the homogeneous (or uniform) and the non-homogeneous (or non-uniform) traffic load scenarios in a multi-cell environment.

How this classification was reachedexpand
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.
