Transcoding-Free Voice Services over GEO Satellites: A Comparative Guide to Heuristic, Learning, and Optimal Approaches

This repository reproduces the numerical evaluation of transcoding-free GEO voice call setup optimization. It models stochastic GEO impairments (delay, jitter, packet loss) and varying GEO satellite transmission rates (0.8-4.0 Kbps). via Monte Carlo sampling and compares Enhanced ROHC, Centralized Linear Programming, and Reinforcement Learning approaches for header and IMS signaling efficiency. The scripts output the key plots used in the manuscript, including reduction ratios, end-to-end signaling size, and runtime trends
