Resource Optimization for Cognitive Satellite Systems with Incumbent Terrestrial Receivers

International audienceWe address the resource optimization issue for communications from terrestrial users to a multi-beam satellite when the bandwidth is shared with incumbent primary terrestrial systems. As a consequence, the satellite system is limited by interference temperature in order not to disturb the incumbent systems. Compared to the state of the art, we propose a relevant way to manage the interference constraints on the incumbent systems. Simulations exhibit a substantial gain in data rate when the number of incumbent systems grows
