Radio frequency interference monitoring system for weather satellite ground stations: Challenges and opportunities

摘要

With the exploding popularity of all things wireless, the radio spectrum has become a scarce commodity. Consequently, spectrum sharing, as a means to enhance efficiency in spectrum use has become closer from theory to practice. However, there are several challenges that need to be addressed before spectrum sharing becomes reality. One of the challenges of this sharing scheme is how we monitor the spectrum of the incumbent user for potential radio frequency interference and subsequently, how we do enforcing, and implementing of spectrum access policies. In this work we are trying to address the challenges of spectrum monitoring as it was evidenced in practice. Since such efforts of spectrum sharing have been very few in practice, our observations can provide guidance for future development of spectrum monitoring and policy making.
