An Efficient Partner Selection Method to Overcome the Interference Effect in Wireless Networks
IEEE Access, 2019 In this paper, through a mathematical analysis of the overall links capacity equation, we present an efficient partner selection criterion in a cooperative communication scheme with a time-varying fading channel and severe interference on the cooperative

Energy efficiency of some non-cooperative, cooperative and hybrid communication schemes in multi-relay WSNs [PDF]
, 2013 In this paper we analyze the energy efficiency of single-hop, multi-hop, cooperative selective decode-and-forward, cooperative incremental decode-and-forward, and even the combination of cooperative and non-cooperative schemes, in wireless sensor ...

A Quantum Multiparty Packing Lemma and the Relay Channel [PDF]
, 2020 Optimally encoding classical information in a quantum system is one of the oldest and most fundamental challenges of quantum information theory. Holevo's bound places a hard upper limit on such encodings, while the Holevo-Schumacher-Westmoreland (HSW ...

PERFORMANCE ANALYSIS OF COOPERATION SCHEMES IN EAVESDROPPER ASSISTED RELAY CHANNEL [PDF]
ICTACT Journal on Communication Technology, 2014 The prominence of the wireless communication has been urging the monotonically increasing demand of security and privacy. In wireless systems, the notion of perfect secrecy of information with respect to illegitimate nodes can be ensured via physical ...

Robust Transceiver Design for IRS-Assisted Cascaded MIMO Communication Systems
Sensors, 2022 Intelligent reconfigurable surfaces (IRSs) have gained much attention due to their passive behavior that can be a successor to relays in many applications. However, traditional relay systems might still be a perfect choice when reliability and throughput

Delay-universal decode-and-forward relaying
2011 Australian Communications Theory Workshop, 2011 We study delay-universal sequential streaming over discrete memoryless three-terminal relay networks, and propose a decode-and-forward relaying scheme. We derive upper bounds on the error performance of the proposed system, which assists in system design and analysis.

Multipair Two-Way DF Relaying With Cell-Free Massive MIMO
IEEE Open Journal of the Communications Society, 2021 We consider a two-way half-duplex decode-and-forward (DF) relaying system with multiple pairs of single-antenna users assisted by a cell-free (CF) massive multiple-input multiple-output (mMIMO) architecture with multiple-antenna access points (APs ...

NOMA-Based User Cooperation With Incremental Hybrid Forwarding Protocols
IEEE Open Journal of the Communications Society, 2021 In this paper, we investigate the performance of a non-orthogonal multiple access (NOMA) wireless system, in which signal transmission of a far user is assisted by a near user.

Optimal Routing for the Gaussian Multiple-Relay Channel with Decode-and-Forward [PDF]
, 2007 In this paper, we study a routing problem on the Gaussian multiple relay channel, in which nodes employ a decode-and-forward coding strategy. We are interested in routes for the information flow through the relays that achieve the highest DF rate.
