Simulation of the achievable indoor MIMO capacity by using an adaptive phased-array
Bibliographic record
Abstract
For a scenario-specific (4,4) multiple-input-multiple-output (MIMO) system in a corridor, we predict the channel matrix between the transmit and receive ports through image ray tracing (IRT) simulations. The physical arrays at the transmit/receive ends are 4 linear equally spaced /spl lambda//2-dipoles (vertically polarized, horizontally arranged and /spl lambda//2 separated) connected to the transmit/receive ports either directly (separate /spl lambda//2-dipole patterns) or through a static/adaptive beamforming network (collocated patterns). For collocated radiation, we use either static patterns (Butler beamformer) or adaptive patterns (collocated phased-array). Accordingly, we show the capacity improvement through adaptive patterns assuming a narrow-band frequency-flat channel (2.4 GHz operating frequency) for each scenario.

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.
