A hybrid spectrum access strategy which is different from traditional underlay or overlay
strategy is proposed for cognitive radio networks. In proposed strategy, the secondary users …

In this paper, a novel closed form expression for the effective capacity (EC) over the α‐η‐
μ/Lognormal and α‐κ‐μ/Lognormal composite fading channels has been derived. Using the …

The effective capacity of communication systems over generalised κ–μ shadowed fading
channels is investigated. A novel and analytical expression for the exact effective capacity is …

This work proposes a covert communication scheme in a cognitive radio network where a
secondary transmitter (ST) transmits confidential information to a secondary receiver under …

In this paper, the bit error rate (BER) performance of a full-duplex (FD) overlay cognitive
radio (CR) network with linear/nonlinear energy harvesting (EH) capability is investigated …

Light Fidelity (LiFi) uses light emitting diodes (LEDs) for high speed wireless
communications. Since employing a different range of the electromagnetic spectrum from …

To tackle the challenging secrecy communication problem in energy harvesting cognitive
radio networks, this paper considers an overlay system with one energy harvesting …

Intelligent reflecting surface (IRS) is widely recognized as a promising technique to enhance
the system performance, and thus is a hot research topic in future wireless communications …

Physical-layer security (PLS) for an underlay cognitive radio network (CRN)-based
simultaneous wireless information and power transfer (SWIPT) over cascaded κ-µ fading …

A new expression for the Cumulative Distribution Function (CDF) of the Joint Fading and
Two-path Shadowing (JFTS) distribution is derived in this paper. The derived theoretical …
