The performance of the cognitive non-orthogonal multiple access (NOMA) systems with random locations is examined in the present paper. More precisely, the positions of the secondary receivers (SRs) are randomly distributed inside a disk with the cent

Recently, mobile edge computing (MEC) has been proposed to improve wireless devices’ computational capabilities by offloading computation-intensive tasks to a network-edge server. Analytical research indicates that the application of non-orthogonal

Limited power and computational resources make the employment of complex classical encryption schemes unrealistic in resource-limited networks, e.g., the Internet of Things (IoT). To this end, physical layer security (PLS) has shown great potential i

This work investigates joint localization-synchronization and tracking in 5G and beyond. In particular, we target realistic circumstances where the theoretical assumptions of a perfect synchronous system and ideal transceivers no longer exist. We tak

This paper investigates the physical layer security (PLS) of non-orthogonal multiple access (NOMA)-enabled overlay cognitive radio networks (NOMA-OCRNs), considering multiple non-colluding eavesdroppers. Here PLS is evaluated in terms of: (i) secrecy

Orthogonal frequency-division multiplexing (OFDM) is a key technology for cellular and Wi-Fi systems, but its performance may be degraded by hardware impairments. Existing works focus mostly on single hardware impairment in OFDM systems, without cons
