In this paper, we propose an underlay two‐way relaying scheme with the successive
interference cancellation (SIC) solution in which two secondary sources transmit …

The fifth-generation (5G) wireless cellular networks aim to increase the users' capacities and
quality of experience as well as to integrate different wireless bands and modes of access …

The limitation of the radio spectrum and the rapid growth of communication applications
make optimal usage of radio resources essential. Cognitive radio (CR) is an attractive …

In this article, we study an orthogonal frequency division multiplexing‐based underlay
cognitive two‐way amplify‐and‐forward (AF) relay network. We assume a system model …

Several works have studied relaying in cognitive radio networks in terms of outage
probability. The main challenge in such works is finding a mathematical expression for this …

In this paper, we propose and analyze two important secure performance metrics of cluster-
based multi-hop relay networks with friendly jamming nodes under the presence of multi …

This paper analyses the outage performance of a multihop relay-based cognitive radio
network under imperfect channel state information. A backoff power control scheme is …

This study investigates the outage performance of an underlaying wireless-powered
secondary system that reuses the primary users'(PU) spectrum in a multiple-input multiple …

The relentlessly increasing number of small-sized devices with limited powering and
computational capabilities requires the adoption of new approaches to spectrum access. In …

In the underlay spectrum sharing approach, cognitive radios have limited coverage area to
keep interference protection for the licensed users. Multiple cooperative relays have shown …
