Non-orthogonal multiple access (NOMA) has been integrated with beamspace multi-input multi-output (MIMO) to enhance system spectrum efficiency (SE) by serving more than one user per dedicated radio frequency (RF) chain. However, balancing the system

Energy efficiency (EE) is considered as one of the pivotal uplink (UL) performance metrics for 5G dense networks. It consists of two conflicting objectives that are recognised as benefit-cost ratio: spectral efficiency and energy consumption. Accordi

Cognitive radio (CR) is wireless communication system that aims to introduce service to unlicensed users or secondary users (SUs) without harming operation of licensed users or primary users (PUs). Hence, the idea behind CR is to exploit unused resou
