Design and Implementation of Rolling Shutter MIMO-OFDM scheme for Optical Camera Communication System
Bibliographic record
Abstract
Orthogonal Frequency-Division Multiplexing (OFDM) is known as the digital multi-carrier modulation technology, which has a lot of advantages compared with single-carrier modulation. OFDM is deployed for broadband wireless communication and broadband wired communication to debate with Inter-Symbol Interference. Currently, the Visible Light band was researched in place of RF band, which shown some applicants: Visible Light Communication (VLC), Optical Camera Communication (OCC), and Light Fidelity (LiFi). The OFDM for LiFi system is known with a lot of schemes (ACO-OFDM, DCO-OFDM. …), however, applying OFDM waveforms for Optical Camera Communication is not known much due to difficulty to deploy. MIMO techniques are known as the techniques to increase the data rate for OCC system. The Rolling Shutter MIMO OFDM technique based on the rolling shutter phenomenon will be presented in this study.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
