Narrowband signal detection in correlated Rayleigh fading with a moving antenna
Bibliographic record
Abstract
The performances of a single moving antenna receiver in detecting a narrowband signal in a correlated Rayleigh fading is considered. The single moving antenna captures spatial samples during antenna displacement that provides a realization of a synthetic antenna array. It is shown that there is a net processing gain in applying synthetic antenna array over keeping antenna stationary. This processing gain is subject to have uncorrelated signals at different antenna position. This paper examines the performance of synthetic array in correlated Rayleigh fading environment. An optimum detector based on estimator-correlator (EC) is developed and its performance is compared with that of non-coherent suboptimal equal-gain (EG) combiner in different channel correlation scenarios. An extensive set of measurements based on CDMA-2000 pilot signals using stationary and moving antennas are used to experimentally verify these theoretical findings.

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.
