Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

Cognitive radio (CR) is an effective solution to improve the spectral efficiency (SE) of
wireless communications by allowing the secondary users (SUs) to share spectrum with …

In this work, we study the statistically robust beamforming design for an intelligent reflecting
surfaces (IRS) assisted multiple-input single-output (MISO) wireless system under imperfect …

Resource allocation (RA) is a key technique to guarantee the quality of service of users and
maximize the system capacity in cognitive nonorthogonal multiple access (NOMA) networks …

Essentialists maintain that at least some individuals or kinds have essences. This raises an
important question: how do we come to know what the essence of something is? Unlike the …

Large-scale antennas are crucial for next generation wireless communication systems as
they improve spectral efficiency, reliability and coverage compared to the traditional ones …

Cognitive multiple-input/multiple-output (MIMO) has been studied as a solution to improve
spectrum utilization via dynamic spectrum sharing technology. In cognitive MIMO systems, it …

Spectrum sharing is essential to support high wireless data rates and a large number of
wireless connections by the future technologies in the limited spectrum that is available. In …
