DESIGN AND ANALYSIS OF COGNITIVE MASSIVE MIMO NETWORKS WITH UNDERLAY SPECTRUM SHARING
… (2) proposing a new wireless-powered underlay cognitive massive MIMO system model, as the secondary user nodes is empowered by the ability to efficiently harvest energy from the primary user transmissions, and then access and utilize the primary network spectrum for information …

Relay Selection Strategies for Multi-hop Cooperative Networks
… also investigate relay selection strategies in underlay spectrum sharing cognitive relay networks. We consider a two-hop DF cognitive relay network with a constraint on the interference to the primary user. The outage probability of the secondary user and the interference probability at the …

Precoder Design for Cooperative Cognitive Radio Systems
… at the source and relay nodes in cooperative underlay CR systems assumption are studied with an aim of achieving maximum possible throughput for the secondary system for two different scenarios: one with multiple secondary relay nodes with a single antenna at each of the source, relay and …

Spectrum sharing for multi-user massive MIMO networks
… by investigating the impact of employing an underlay spectrum sharing (USS) scheme on the performance of two massive multi-input-multi-output (MIMO) networks. We explore an USS approach where a multi-user massive MIMO network (primary network (PN)), i.e., the owner of the frequency spectrum, …
