The study of cognitive radio (CR) techniques in SatCom research activities is still in its infancy. In this context, the CoRaSat (Cognitive Radio for Satellite Communications) project aims, for the first time, at investigating, developing, and demonstrating CR techniques in SatCom systems for a more efficient utilization of spectrum. In this chapter, an overview of the scenarios analyzed in the CoRaSat project is provided. In particular, Ka-, Ku-, S-, and C-band scenarios are considered and characterized taking into account the market and business frameworks, the regulatory and standardization frameworks, and the technology framework. The methodology applied in the CoRaSat project for scenario selection is provided as well, and preliminary system architecture is defined for the selected Ka-band scenarios. Useful conclusions for further analysis are also drawn.

Abstract
The study of cognitive radio (CR) techniques in SatCom research activities is still in its infancy. In this context, the CoRaSat (Cognitive Radio for Satellite Communications) project aims, for the first time, at investigating, developing, and demonstrating CR techniques in SatCom systems for a more efficient utilization of spectrum. In this chapter, an overview of the scenarios analyzed in the CoRaSat project is provided. In particular, Ka-, Ku-, S-, and C-band scenarios are considered and characterized taking into account the market and business frameworks, the regulatory and standardization frameworks, and the technology framework. The methodology applied in the CoRaSat project for scenario selection is provided as well, and preliminary system architecture is defined for the selected Ka-band scenarios. Useful conclusions for further analysis are also drawn.
