Abstract
A wideband TDMA system for high rate communications with an adaptive antenna array at base stations is proposed. This system is based on the recursive least squares (RLS) adaptive algorithm. The adaptive array provides a way to suppress the co-channel interference (CCI) and intersymbol interference (ISI). A method to generate a reference signal for the RLS algorithm is presented. We also propose two multipath diversity schemes, tapped delay lines (TDL) and parallel array processors (PAP), to cope with the urban cellular multipath environment and enhance the performance of the adaptive array system. The performance of the proposed system is quantified by comparison with an one-element omnidirectional antenna system. It is shown that the adaptive antenna system has a substantial improvement in performance over the one-element antenna system. Two different multipath diversity schemes are compared corresponding to signal-to-noise ratio (SNR) and multipath angle of arrival (AOA) spread. The simulation results illustrate that, for a wide AOA spread, the PAP outperforms the TDL scheme. However, the TDL is a better scheme for a narrow AOA spread.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
