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.

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 ...

Relay-Induced Error Propagation Reduction for Decode-and-Forward Cooperative Communications [PDF]

, 2010
An attractive hybrid method of mitigating the effects of error propagation that may be imposed by the relay node (RN) on the destination node (DN) is proposed.

Diversity-Multiplexing Tradeoffs in MIMO Relay Channels

, 2008
A multi-hop relay channel with multiple antenna terminals in a quasi-static slow fading environment is considered. For both full-duplex and half-duplex relays the fundamental diversity-multiplexing tradeoff (DMT) is analyzed.

Mobile User Connectivity in Relay-Assisted Visible Light Communications

Sensors, 2018
In this paper, we investigate relay-assisted visible light communications (VLC) where a mobile user acts as a relay and forwards data from a transmitter to the end mobile user.

Energy-Efficient Cooperative Protocols for Full-Duplex Relay Channels

, 2013
In this work, energy-efficient cooperative protocols are studied for full-duplex relaying (FDR) with loopback interference. In these protocols, relay assistance is only sought under certain conditions on the different link outages to ensure effective ...

Optimal Distributed Resource Allocation for Decode-and-Forward Relay Networks [PDF]

, 2013
This paper presents a distributed resource allocation algorithm to jointly optimize the power allocation, channel allocation and relay selection for decode-and-forward (DF) relay networks with a large number of sources, relays, and destinations. The well-

Molecular characterisation of human penile carcinoma and generation of paired epithelial primary cell lines

Molecular Oncology, EarlyView.
Generation of two normal and tumour (cancerous) paired human cell lines using an established tissue culture technique and their characterisation is described. Cell lines were characterised at cellular, protein, chromosome and gene expression levels and for HPV status.
