Abstract
This paper investigates the average bit error rate (BER) performance of reconfigurable single-input single-output (RE-SISO) antenna systems in the clustered channel model. The main focus of the paper is to evaluate the impacts of angle of arrival (AoA) estimation errors, angular spread and antenna beamwidth on the performance of a reconfigurable system. In particular, the BER for the RE-SISO systems is presented under perfect AoA knowledge at the receiver. Then, an analytical expression for the BER of the system is derived in the presence of AoA estimation errors. Along with this, the effects of angular spread and antenna beamwidth on the system performance are examined for both perfect and imperfect AoA estimation scenarios. The results indicate that the effect of AoA estimation error is more significant when the cluster angular spread is small. The same conclusion can be made for the antenna beamwidth.

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
