Efficient evaluation of adaptive digital beamforming for multi-service provision in a cellular CDMA system
Bibliographic record
Abstract
In future wireless communication scenarios, there will be a greater need for multimedia access, with the transfer of data being of at least equal importance to voice communications. Cell capacity in a CDMA communication system can be increased through the use of base station antenna arrays and digital beamforming. We explore cell capacity values for combined services (voice and data) over the reverse link of a CDMA system and investigate the improvements that can be obtained from beamforming. Our simulated and predicted results for bandwidths of 1.2288 MHz (narrowband IS-95) and 4.9152 MHz (wideband CDMA) show good agreement with each other. The wider bandwidth appears to be more appropriate for multi-service provision due to an observed constant data throughput as the number of data mobiles is varied. An increase of approximately 50% in average throughput was observed for 2 elements and 135% for 3 elements, as compared to the single element case for 4.9152 MHz.

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.
