Abstract
An ASIC implementation of a WCDMA mobile terminal with 2-dimensional adaptive antenna-rake combining is presented in this paper. System analysis shows that adaptive antenna-rake combining techniques can significantly enhance the performance and capacity of cellular systems compared to conventional CDMA systems. A hardware efficient receiver architecture is implemented supporting both maximal ratio combining (MRC) and least mean squares (LMS) algorithm. Moreover, the proposed architectures allows for a dynamic and flexible allocation of available processing resources (total of 20 fingers) to different antennas and multipaths based on the instantaneous channel profile. The presented receiver can operate in both normal and space time transmit diversity (STTD) modes. The system was implemented in a 0.18/spl mu/m CMOS process and the improvement was validated through real-time field trials.

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
