Thanks to the development in the wireless communication technologies and the microelectronics domain, Wireless Sensor Networks (WSNs) are more and more omnipresent. The most important challenge of WSN is how to extend its ...

Although the progress in understanding 5G and beyond techniques such as Non-Orthogonal Multiple Access (NOMA) and full-duplex techniques has been overwhelming, still analyzing the security aspects of such systems under ...

In this paper, a Decode-and-Forward (DF) relaying system for Non Orthogonal Multiple Access (NOMA) networks is considered, where the transmitted information between the relay and NOMA users can be overheard by an eavesdropper. ...

A method for components instantaneous frequency (IF) estimation of multicomponent signals in low signal-to-noise ratio (SNR) is proposed. The method combines a new proposed modification of a blind source separation (BSS) ...

With the witnessed exponential growth of Internet of Things (IoT) nodes deployment following the emerging applications, multiple variants of technologies have been proposed to handle the IoT requirements. Among the proposed ...

In limited space scenarios, the antennas in the multiantenna cognitive radio (CR) system are closely spaced and often experience correlation among them. In this work, the secrecy performance of correlated multiantenna CR ...

In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-aided wireless communication system in the presence of an eavesdropping user. Specifically, we assume that the RIS is placed ...

In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...

In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...

In this paper, we investigate the impact of feedback delay and channel estimation error (CEE) on the performance of wireless multi-user decode-and-forward (DF) relay systems in independent and non identically distributed ...
