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) has been considered as a potential candidate for addressing the
spectrum scarcity problem of future wireless networks. Since its conception, several …

This article studies and derives beamforming design in a dual-functional radar-
communication (DFRC) multiple-input-multiple-output system. We focus on a scenario …

In this paper, a novel dynamic power allocation scheme is proposed to downlink and uplink
non-orthogonal multiple access (NOMA) scenarios with two users for more flexibly meeting …

Nonorthogonal multiple access (NOMA) represents a paradigm shift from conventional
orthogonal multiple-access (MA) concepts and has been recognized as one of the key …

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 survey, we present a comprehensive list of major known security threats within a
cognitive radio network (CRN) framework. We classify attack techniques based on the type …

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 …

Traditional spectrum allocation policies may result in temporarily unused radio spectrum.
Cognitive radio (CR) has emerged as a promising technology to exploit the radio spectrum …

Abstract The US Federal Communications Commission (FCC) defines white space as the
channels that are unused at a specific location or time. For futuristic cognitive radio (CR) …
