Power Minimization in Wireless Network Virtualization with Massive MIMO

This thesis aims to study wireless network virtualization and particularly its challenges when it is applied to massive MIMO technology. Virtualization has been well studied in the wired networks and computational resources. However, when it comes to wireless networks new challenges arise. We consider virtualization in the context of massive MIMO technology and develop a novel precoding schemes to abstract and share a massive MIMO base station with the objective of minimizing power. This problem is investigated when perfect channel information is available and when is not. Furthermore, we show that our formulation is general enough to be easily extended to multi-cell and address some concerns of the service provider. We obtain optimal precoding when perfect channel information is available and a nearly optimal solution when the channel information is corrupted.M.A.S.2018-11-03 00:00:0
