The integration of cognitive radio (CR) technology and non-orthogonal multiple access
(NOMA) techniques, referred to as CR-based NOMA systems, has been recently configured …

Non-orthogonal multiple access (NOMA) is one of the most effective techniques for meeting
the spectrum efficiency (SE) requirements of 5G and beyond networks. This paper presents …

One of the greatest ways to guarantee that networks designed for fifth generation (5G) and
beyond reach the required levels of spectrum efficiency (SE) is through nonorthogonal …

We propose short packet communication in an underlay cognitive radio network assisted by
an intelligent reflecting surface (IRS) composed of multiple reconfigurable reflectors. This …

Novel radio access strategies must be developed to support an unprecedented number of
connected devices to increase radio spectral efficiency of 5G and outside, and non …

Cooperative communication by employing unmanned aerial vehicle (UAV)-based relays
with radio-frequency (RF) energy harvesting (EH) has been emerged as a prominent …

Non-orthogonal multiple access (NOMA) along with cognitive radio (CR) have been recently
configured as potential solutions to fulfill the extraordinary demands of the fifth generation …

The integration between cognitive radio (CR) technology and non-orthogonal multiple
