Sum Rate Maximizing Multigroup Multicast Beamforming under Per-antenna Power Constraints
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
A multi-antenna transmitter that conveys independent sets of common data to distinct groups of users is herein considered, a model known as physical layer multicasting to multiple…
Multicast Multigroup Beamforming under Per-antenna Power Constraints
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
Linear precoding exploits the spatial degrees of freedom offered by multi-antenna transmitters to serve multiple users over the same frequency resources. The present work focuses o…
Weighted Fair Multicast Multigroup Beamforming under Per-antenna Power Constraints
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
A multi-antenna transmitter that conveys independent sets of common data to distinct groups of users is considered. This model is known as physical layer multicasting to multiple c…
Multicast Multigroup Precoding and User Scheduling for Frame-Based Satellite Communications
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
The present work focuses on the forward link of a broadband multibeam satellite system that aggressively reuses the user link frequency resources. Two fundamental practical challen…
Frame Based Precoding in Satellite Communications: A Multicast Approach
Dimitrios Christopoulos, Symeon Chatzinotas, Bjorn Ottersten
In the present work, a multibeam satellite that employs aggressive frequency reuse towards increasing the offered throughput is considered. Focusing on the forward link, the goal i…
