Spectrum inference, also known as spectrum prediction in the literature, is a promising
technique of inferring the occupied/free state of radio spectrum from already …

In this paper, we introduce a new spatial spectrum-sharing strategy for massive multiple-
input multiple-output (MIMO) cognitive radio (CR) systems. Different from the conventional …

Security is a challenging issue for cognitive radio (CR) to be used in future 5G mobile
systems. Conventionally, interference will degrade the performance of a primary user (PU) …

The 5G wireless cellular networks are evolving, to meet the drastic subscriber demands in
near future. This is accompanied with a rise in the energy consumption in cellular networks …
