Joint Beamforming for Multicell Multigroup Multicast with Per-cell Power Constraints
IEEE Transactions on Vehicular Technology, 2014This paper considers a joint beamforming design problem in the multicell multicast system with multiple groups that provide different multicast services. Inspired by previous works in the literature, we apply semidefinite relaxation (SDR) to perform joint beamforming design among the cooperating base stations.

Multicast multigroup precoding for frame-based multi-gateway satellite communications
2016 8th Advanced Satellite Multimedia Systems Conference and the 14th Signal Processing for Space Communications Workshop (ASMS/SPSC), 2016The present work focuses on the forward link of fixed multibeam broadband satellite systems which employ aggressive frequency reuse patterns in the user-link. For such scenarios, the state-of-the art frame based precoding methods can improve the system performance, exploiting the super framing structure of the latest physical layer evolutions in ...
