Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

In this paper, we study the performance improvement methods for a cell-edge user of two-
user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end …

In this article, we propose an efficient deep-neural-network-based relay selection (DNS)
scheme to evaluate and improve the end-to-end throughput in wireless-powered cognitive …

In this paper, we study the performance of a cell-edge user in a two-user multiple-input
single-output nonorthogonal multiple access (MISO-NOMA) system. Since the outage …

Increasing number of devices connected to the networks, applications and demands of new
generation wireless communications cause very high energy consumption resulting in large …

The efficient and effective framework for next-generation (5G and beyond 5G) wireless
networks should include mission-critical aspects such as ultralow latency (ms), ultrahigh …

In this paper, we consider an energy efficient resource allocation technique for a hybrid time
division multiple access (TDMA)-non-orthogonal multiple access (NOMA) system. In such a …

In this article, we investigate the performance of a piece-wise linear model of energy
harvesting-based multiuser overlay spectrum sharing system. Herein, an energy …

The study of the effects of Nakagami-m fading channels with both integer and non-integer m
plays an important role in the design of practical wireless systems. In this paper, we …

Recently, energy harvesting (EH) via radio-frequency (RF) signals in wireless relay networks
has been attracting a lot of interest, especially for supplying the energy to relay nodes in IoT …
