Abstract
Abstract We present a unified construction of full‐diversity space‐time block codes (STBC) called orthogonality‐embedded space‐time (OEST) codes. Other existing STBC, including orthogonal, quasi‐orthogonal and rate‐one linear threaded algebraic space‐time (LTAST) codes, can also be derived from OEST codes. The new OEST construction is of the form ${\sum} (A_k\otimes C_k + B_k\otimes C_k^{\rm H})$ , where A k and B k are linear‐dispersion matrices of orthogonal STBC and C k s are circulant matrices. The circulant matrices encode the data vectors, which can be completely separately detected at the receiver, greatly reducing the decoding complexity. For the same number of transmit antennas, several variants of OEST codes can be constructed allowing a tradeoff among the rate, performance and decoding complexity. A new rate‐one STBC derived from OEST codes, called semi‐orthogonal algebraic space‐time codes, is shown to achieve near capacity of multi‐input single‐output channels and performs better than several existing STBC.

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 it
