OFCDM-based small femtocells embedded in OFDM-based macro cellular network
Bibliographic record
Abstract
To extend indoor coverage and offload cellular network traffic, femtocell technology becomes more promising. Multi-carrier spread spectrum technology has proven to be effective in multiple access and provides robust performance in fading radio channels. In this paper, VSF-OFCDM is utilized for sub-carrier allocation with two dimensional spreading (2D) for femto users (FUEs) in small cells that are deployed within an OFDMA macro network. The performance of femto/macro hybrid network is investigated by deriving closed form expressions for the SINR for FUEs and macro users (MUEs) in uplinks, that are impacted by different types of interferers, 2D spreading factors and load conditions. We also evaluate the BER performance of FUEs and MUEs through Monte Carlo simulation in interference- and noise-limited scenarios for different parameters.

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.
