In this paper, we apply a reconfigurable intelligent surface (RIS) to a two-way (TW) full-
duplex (FD) wireless communication system, where a RIS has N reflecting elements and …

Cognitive radio networks (CRN) make use of dynamic spectrum access to communicate
opportunistically. Unlicensed users severely affect the spectrum sensing outcomes in CRN …

Recent studies in information computation technology (ICT) are focusing on Next-generation
networks, SDN (Software-defined networking), 5G, and 6G. Optimal working mode for device …

In this paper, we exploit the benefits of full-duplex (FD) transmission and reconfigurable
intelligent surfaces (RISs) by considering a bidirectional full-duplex wireless communication …

For the sake of fulfilling the ever-increasing demands on the Internet of Things (IoT)
applications, researchers are implementing Cognitive Radio (CR) technology in Ad-Hoc …

Recent developments of self-interference suppression techniques have enabled practical
implementations of full-duplex (FD) cognitive-radio (CR) communication systems. Such …

Most autism centers in Arabic countries rely on manual techniques in teaching children the
basics of language, math, and social skills. Actually, these techniques may be limited in …

Wireless communication demands rapidly increase due to the increase of Internet of Things
applications, which leads researchers to build secondary networks that exploit the spectrum …

In this paper, an intelligent reflecting surface (IRS), which consists of L reflecting elements
(REs), is utilized to improve the coverage and reliability of half-duplex relaying (HDR) and …

Hardware impairments (HI) due to imperfect manufactured electronic parts degrade the
performance of wireless systems. In this paper, we consider a bidirectional full-duplex (FD) …
