An Efficient Partner Selection Method to Overcome the Interference Effect in Wireless Networks

open access: yesIEEE 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

PERFORMANCE ANALYSIS OF COOPERATION SCHEMES IN EAVESDROPPER ASSISTED RELAY CHANNEL [PDF]

open access: yesICTACT 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

open access: yesSensors, 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

Smart Decode-and-Forward Relaying with Polar Codes [PDF]

open access: yesIEEE Wireless Communications Letters, 2014
Polar codes have recently been proven to be capacity achieving for the physically degraded relay channel and relevant coding schemes have been proposed in the literature. In this paper, we deal with the design of polar codes in decode-and-forward relaying and prove that the selective transmission of the relay to the destination, based on the decision ...

Multipair Two-Way DF Relaying With Cell-Free Massive MIMO

open access: yesIEEE 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

open access: yesIEEE 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.

Mobile User Connectivity in Relay-Assisted Visible Light Communications

open access: yesSensors, 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.
