Abstract

This thesis investigates the performance of various cooperative spectrum sensing algorithms applied in Low-Earth-Orbit satellite communication systems. With the exceptional growth of satellite launches, efficient spectrum utilization has become crucial to mitigating communication bottlenecks. Through simulation-based evaluation, key spectrum sensing algorithms - including energy-detection, absolute-value-cumulation, robust-sensing, MinMax-sensing and Z-score-sensing - were analyzed across laplacian and gaussian noise models, signal types, and cooperation scenarios. Additionally, the thesis reviews a proposed channel model to simulate satellite-to-ground communication path loss. However, challenges in parameter estimation and reproducibility prevented its successful implementation and experimental application in Berlin. Results reveal that Robust-sensing and Z-score-sensing consistently achieve superior detection probabilities under varying signal-to-noise ratios, especially when complemented by cooperative methods like AND and Majority voting. The thesis provides a foundation for developing robust, scalable algorithms for dynamic, noise-prone environments, contributing to the efficient management of the radio frequency spectrum in satellite communication.
