Abstract
This paper serves as a tutorial on antenna selection for multiple-input multiple-output (MIMO) communication systems. We consider the impact of antenna selection on the system capacity, as well as on the performance of the space-time trellis codes (STTCs) and space-time block codes (STBCs). We consider various fading channel models, including fast, block and slow fading. We also consider two selection criteria, namely, the one that maximizes the channel capacity and the one that maximizes the instantaneous received signal-to-noise ratio (SNR). We show that little capacity loss is incurred with antenna selection. We also demonstrate that the diversity order is maintained with antenna selection for STTCs only for special cases, whereas the diversity order is maintained with antenna selection for orthogonal STBCs for all channel models. This makes OSTBCs very attractive when antenna selection is considered. We finally consider the effect of some system nonidealities on the performance with antenna selection

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
