Multi-Gateway Cooperation in Multibeam Satellite Systems
Gan Zheng, Symeon Chatzinotas, Bjorn Ottersten
Multibeam systems with hundreds of beams have been recently deployed in order to provide higher capacities by employing fractional frequency reuse. Furthermore, employing full freq…
Generic Optimization of Linear Precoding in Multibeam Satellite Systems
Gan Zheng, Symeon Chatzinotas, Bjorn Ottersten
Multibeam satellite systems have been employed to provide interactive broadband services to geographical areas under-served by terrestrial infrastructure. In this context, this pap…
Robust Monotonic Optimization Framework for Multicell MISO Systems
Emil Björnson, Gan Zheng, Mats Bengtsson +1
The performance of multiuser systems is both difficult to measure fairly and to optimize. Most resource allocation problems are non-convex and NP-hard, even under simplifying assum…
