Efficient design of reconfigurable intelligent surface assisted multi-group multicast beamforming
(2023-09-01)
This thesis considers a multi-group multicasting scenario facilitated by a reconfigurable intelligent surface (RIS). We propose low-complexity scalable algorithms for the joint design of the base station (BS) multicast ...
Spectrum sharing for multi-user massive MIMO networks
(2023-12-01)
In this dissertation, we propose a creative approach to advance 5G network technologies by investigating the impact of employing an underlay spectrum sharing (USS) scheme on the performance of two massive multi-input-multi-output ...
