A Dynamic Spot Diffusing Architecture for Indoor Wireless Optical Communications
Bibliographic record
Abstract
In this work we introduce a novel high-speed architecture for indoor wireless optical communications termed the dynamic spot diffusing (DSD) architecture. In this configuration the transmitter modulates data onto a spot on the ceiling which moves in a closed path. An imaging receiver acquires data whenever the transmitter spot is in its field-of-view (FOV). We show that this technique is more flexible, has greater multipath immunity, permits higher data rates and has a simpler transmitter than previously defined multi-spot and diffuse architectures. We compare the available channel capacities for a family of spot paths and receiver FOV. Instead of synchronizing to the spot location, rateless erasure correcting codes are applied to approach the capacity of the simulated DSD links. In a 6×6×3 m room, simulated data rates vary between 12.1 Mbps to 40 Mbps at different positions using a single 100 Mbps transmitter and the designed erasure correction code.

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.
