Demonstration of Concurrent Dual-Band 1-bit Envelope Delta-Sigma Modulated LTE Radio-over-Fiber Transmission
Bibliographic record
Abstract
With the growing demand for cloud radio access networks, mobile fronthaul networks must stay adaptable, efficient and cost-effective. To simplify fronthaul transmission systems, 1-bit delta-sigma modulation (DSM) radio over fiber (RoF) transmission has been considered promising, in which 1-bit DSM technique is used to simplify remote radio units. Moreover, carrier aggregation is a key technique for increasing fronthaul transmission capacity. This work demonstrates, for the first time, concurrent dual-band 1-bit envelope DSM 64-QAM 20-MHz LTE signals transmitted over RoF system. It is shown that carrier aggregation combined with 1-bit delta-sigma modulation is a possible promising technique for high-capacity fronthaul transmission.

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.
