Abstract
Channels with memory offer higher capacities provided that the system design can take advantage of this memory. In this paper, we study and characterize the dynamics of a correlated Rayleigh fading channel with known phase. The model follows a continuous-time Markov double-chain for the random fading process with the Markov states corresponding to the quantized amplitude levels. The analytical expression for the distribution of the state dwell times is derived. We also calculate the mean dwell times of the Markov states in terms of the fading properties and the quantization level. Observations from simulating a typical land-mobile channel verify that the Markovian dynamics are best represented through a finer quantization of the lower level fading amplitudes.

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
