Uplink/Downlink Reciprocity in VLC Channels and Its Application to Rate Analysis of SLIPT Systems
Bibliographic record
Abstract
In visible light communication (VLC) systems, the uplink and downlink channel gains depend on environmental geometry. This geometric nature induces a relationship between the uplink and downlink VLC channel gains. In this paper, the reciprocity relation between the uplink and downlink VLC channel gains are analyzed. It is shown that the reciprocity relationship can be accurately modeled as affine or polynomial. This reciprocity analysis can be a useful tool that enables several VLC system analysis and design. As an interesting application, using this channel reciprocity and model of the solar cell, the relationship between the downlink rate, harvested power and uplink rate are obtained for a solar cell based VLC-SLIPT system. This enables the formulation of the uplink-downlink rate region for a solar cell-based SLIPT system. The rate region gives the set of all simultaneously achievable rates in the uplink and downlink. The rate analysis, enabled by the reciprocity result, gives the trade-off between downlink and uplink rates that is essential in the system design of solar cell based SLIPT receivers.

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.
