Secure Performance of DF Relaying in Cooperative NOMA over Rician Fading Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
In this paper, a Decode-and-Forward (DF) relaying system for Non Orthogonal Multiple Access (NOMA) networks is considered, where the transmitted information between the relay and NOMA users can be overheard by an eavesdropper. ...
Secrecy performance analysis of half/full duplex AF/DF relaying in NOMA systems over κ−μ fading channels
(
Springer
, 2022 , Article)
Although the progress in understanding 5G and beyond techniques such as Non-Orthogonal Multiple Access (NOMA) and full-duplex techniques has been overwhelming, still analyzing the security aspects of such systems under ...
Multihop transmission strategy using dijkstra algorithm to improve energy efficiency in WSNs
(
Springer Verlag
, 2018 , Conference Paper)
Thanks to the development in the wireless communication technologies and the microelectronics domain, Wireless Sensor Networks (WSNs) are more and more omnipresent. The most important challenge of WSN is how to extend its ...
An efficient algorithm for instantaneous frequency estimation of nonstationary multicomponent signals in low SNR
(2011 , Article)
A method for components instantaneous frequency (IF) estimation of multicomponent signals in low signal-to-noise ratio (SNR) is proposed. The method combines a new proposed modification of a blind source separation (BSS) ...
Adaptive hierarchical cooperative communication using energy harvesting relay
(2013 , Conference Paper)
In this paper, we present an adaptive wireless communication system with energy harvesting relay where, two sources wish to send data to a destination via an energy harvesting relay that utilizes hierarchical constellation. ...
Distributed spectrum sensing of correlated observations in cognitive radio networks
(2013 , Conference Paper)
In this paper, Collaborative Spectrum Sensing (CSS) as one of the most efficient sensing approaches in Cognitive Radio Networks (CRNs) is investigated when the Secondary Users (SUs) observations are assumed to be correlated. ...
Cooperative cognitive relaying under primary and secondary quality of service satisfaction
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
This paper proposes a new cooperative protocol which involves cooperation between primary and secondary users. We consider a cognitive setting with one primary user (PU) and multIPle secondary users (SUs). The time resource ...
Lifetime maximization with predictive power management in selective relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2009 , Conference Paper)
A diversity scheme which exploits the existence of a source-destination path to improve the lifetime and outage probability of a wireless selective relay network with Amplifyand-Forward (AF) relays is proposed and studied. ...
On the synergistic benefits of alternating CSIT for X channel within a four-symbol channel extension
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we investigate the degrees of freedom (DoF) of the two-user single input single output (SISO) X channel with alternating channel state information at the transmitters (CSIT). Three cases are considered for ...
