High Dynamic Range Agile Radio over Fiber Transmitter’s Architectures for 5G/NR Applications
Bibliographic record
Abstract
<title>Abstract</title> In this paper, we proposed a novel radio over fiber (RoF) transmitter architecture to achieve high dynamic range (DR) suitable for millimeter wave (mm-wave) applications, supported by simulation and experimental validations. The designed test benches achieved more than-41 dBc adjacent carrier leakage ratio (ACLR) for a fifth generation/new radio (5G/NR) signal of 100 MHz bandwidth, transmitted in the upper frequency range (FR2) at 28 GHz. The key for this achievement is the utilization of the electrical mixing with proper phase shift before optical modulation. The mixing of the local oscillator (LO) and the intermediate frequency (IF) signals in the electrical domain, reduces the unwanted beating between optical bands prior to the photo-detection stage, hence preventing photodetector saturation, which leads to higher optical-to-electrical conversion.

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.
