Millimeter wave spatial multiplexing: Feasibility and performance of a short range 2×2 link
Bibliographic record
Abstract
In this paper, a 60 GHz short-range spatial multiplexing architecture for a 2 × 2 MIMO (Multiple-Input Multiple-Output) system is proposed and analyzed. High-speed communications can be achieved at 60 GHz thanks to the availability of 7 GHz of unlicensed bandwidth and strong free-space attenuation, allowing efficient spectrum reuse. Spatial multiplexing MIMO techniques can also be used to furher improve the data rate. A computer model using measured results of 8 patches microstrip antenna array for both transmitter and receiver antennas is proposed to analyze a MIMO spatial multiplexing architecture which diagonalize the channel matrix in hardware, by tuning certain physical parameters. This method avoids the conventional MIMO signal processing which requires high speed embedded DSP. Measurement results of the spatial multiplexing systems are also presented. This study proves that the capacity of the proposed MIMO system can be considerably increased compared to SISO (Single-Input-Single-Output) under certain conditions.

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.
