Effect of Correlated Turbulence on Integrated SAG-FSO/SH-FSO/RF Transmission for Satellite Communications
Bibliographic record
Abstract
Free-space optics (FSO) is slated as a promising solution to support extremely high data rates for future satellite communications (SatCom). Nonetheless, FSO transmission is susceptible to atmospheric turbulence impacts. Space-air-ground (SAG) FSO and hybrid single-hop (SH) FSO/radio frequency (RF) transmission systems are suggested to enhance the performance and reliability of FSO-based SatCom systems. They can also be integrated to further improve system performance. Previous work analyzed the performance of the resulting integrated SAG-FSO/SH-FSO/RF transmission system, assuming independent turbulence effects. In this paper, we perform a capacity analysis of the system in the presence of correlated turbulence. A novel analytical expression for the end-to-end ergodic capacity is derived and validated by Monte Carlo simulations. The numerical results demonstrate that, although the correlated turbulence adversely affects its performance, the integrated transmission system can still achieve a considerable capacity gain over existing solutions.

How this classification was reachedexpand
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.
