Security–Reliability Tradeoff Analysis of Multirelay-Aided Decode-and-Forward Cooperation Systems

Security-Reliability Trade-off Analysis of Multi-Relay Aided Decode-and-Forward Cooperation Systems

We consider a cooperative wireless network comprised of a source, a destination and multiple relays operating in the presence of an eavesdropper, which attempts to tap the source-destination transmission. We propose multi-relay selection scheme for protecting the source against eavesdropping. More specifically, multi-relay selection allows multiple relays to simultaneously forward the source’s ...

Cooperation Based on Decode-and-Forward Plus Cooperative Jamming for

We employed node cooperation in a cooperative wireless network to achieve physical layerbased security. The case of a source-destination pair that works with the assistance of multiple cooperating nodes in the presence of an eavesdropper was considered in this study to improve the performance of secure wireless communications. A novel cooperative scheme, called the decode-and-forward plus coope...

Performance Analysis of cooperative SWIPT System: Intelligent Reflecting Surface versus Decode-and-Forward

In this paper, we explore the impacts of utilizing intelligent reflecting surfaces (IRS) in a power-splitting based simultaneous wireless information and power transfer (PS-SWIPT) system and compare its performance with the traditional decode and forward relaying system. To analyze a more practical system, it is also assumed that the receiving nodes are subject to decoding cost, and they are on...

Technical Report: A Unified Framework for Analysis of Path Selection Based Decode-and-Forward (DF) Cooperation in Wireless Systems

Amplify-forward and decode-forward cooperation relying on systematic Luby transform coded hybrid automatic-repeat-request

Systematic Luby transform (SLT) codes constitute rateless codes, which are capable of adaptively adjusting their code rate depending on the channel quality without any explicit channel state information (CSI) at the transmitters. SLTs are also suitable for space time collaboration-aided relay networks. In this study, an iterative decoding-aided SLT scheme is combined with 16 quadrature amplitud...
