In 5G-based cognitive radio, the primary user signal is more active due to the broad
frequency band. The traditional cooperative spectrum sensing only detects one …

In this paper, a wireless energy harvesting and information transfer protocol in cognitive
relay networks is investigated, where an energy harvesting secondary network shares the …

This paper proposes relay selection to increase the physical layer security in multiuser
cooperative relay networks with multiple amplify-and-forward relays, in the presence of …

Direct-conversion radio (DCR) receivers can offer highly integrated low-cost hardware
solutions for spectrum sensing in cognitive radio (CR) systems. However, the DCR receivers …

In this paper, a new mode selection (MS) scheme for device-to-device (D2D) enabled
cellular networks is proposed. The MS is carried out using a predefined signal-to …

In this paper, we study a two-phase underlay cognitive relay network, where there exists an
eavesdropper who can overhear the message. The secure data transmission from the …

In this paper, we study an underlay cognitive energy harvesting decode-and-forward (DF)
relaying communications system with multiple secondary users (SUs) and a primary …

In this paper, we study a cooperative vehicle-to-vehicle (V2V) interference-limited
communication system with decode-and-forward relaying operating over double-Nakagami …

Direct-conversion radio transceivers can offer reprogrammable and low-cost hardware
solutions for full-duplex (FD) cognitive radio networks (CRNs). However, they are …

We investigate the impact of multiple primary users (PUs) and fading on the spectrum
sensing of a classical energy detector (ED). Specifically, we present the novel closed-form …
