Abstract

With the growing amount of satellite traffic an efficient usage of the existing resources, i.e. geostationary arc and available frequency bands, is mandatory. Therefore appropriate monitoring techniques are of paramount importance for reasonable operation of satellite networks. The increase in available computational power enables signal processing tasks that were not even thinkable a decade ago. So it is proposed to apply blind demodulation techniques, suited for implementation on software-defined radio (SDR) platforms, for carrying out the required monitoring tasks. The incorporated algorithms are presented, including performance comparison and remarks on efficient implementation. Finally, the demodulation capabilities of the introduced framework are assessed in terms of the error vector magnitude (EVM).
