This paper investigates the impact of primary network interference on the performance of
cognitive multihop secondary network under various multiple-input multiple-output (MIMO) …

In this paper, the performance of underlay cognitive dual-hop decode-and-forward (DF) multi-
relay networks with best relay selection (BRS) over independent identically distributed (iid) …

In this paper, we evaluate two-way relay communication systems in cognitive radio
environments. The proposed model includes two subsystems: a primary system and a …

In this paper, we present an optimal scheme for power allocation and relay selection in a
cognitive radio network where a pair of cognitive (or secondary) transceiver nodes …

In this paper, we study the performance of simultaneous wireless information and power
transfer (SWIPT) technique in a multi-destination dual-hop underlay cognitive relay network …

In this paper, we consider a cognitive cooperative relay network (CCRN) that utilizes a
decode-and-forward relay in the presence of multiple primary users. Given this system …

In this paper, we consider a multiple‐input multiple‐output (MIMO) cooperative cognitive
radio (CR) system using amplify‐and‐forward protocol under a spectrum sharing scenario …

We consider a multiple‐input and multiple‐output (MIMO) cognitive radio (CR) network with
a MIMO relay that opportunistically accesses the same frequency band as that of a MIMO …

We examine the impact of transmit antenna selection with receive generalized selection
combining (TAS/GSC) for cognitive decode-and-forward (DF) relaying in Nakagami-m fading …

The outage performance of cognitive relay networks (CRNs) for a decode-and-forward (DF)
protocol in a spectrum sharing scenario with orthogonal space-time block code (OSTBC) …
