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 ...

Switching-based cooperative decode-and-forward relaying for hybrid FSO/RF networks
IEEE\/OSA Journal of Optical Communications and Networking, 2019 In this paper, we propose a switching scheme for a hybrid free-space optical (FSO)/radio frequency (RF) system with a selective decode-and-forward (DF) relay network.

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

Power Efficient Decode-and-Forward Cooperative Relaying [PDF]
IEEE Wireless Communications Letters, 2012 Cooperative communications have been proven to be effective in enhancing performance of wireless networks. In this letter, we introduce and propose adaptive relay-selection rules to offer a tradeoff between fairness and energy consumption at each node for a network with multiple, mutually cooperative nodes.

Decode-and-Forward Relaying for Cooperative NOMA Systems With Direct Links
IEEE Transactions on Wireless Communications, 2018 This paper investigates a cooperative non-orthogonal multiple access system, in which a base station communicates with two far users with the aid of a decode-and-forward (DF) relay. Three cooperative relaying schemes, namely, the fixed relaying (FR), the

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

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.
