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 ...
A promising non-orthogonal multiple access based networking architecture: Motivation, conception, and evolution
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
Since it can offer higher spectral efficiency by granting the served data to share the same spectrum resource synchronously, NOMA is considered as a bright multiple access technique for future wireless networks. Accommodating ...
End-to-end performance of transmission systems with relays over Rayleigh-fading channels
(
IEEE
, 2003 , Article)
End-to-end performance of two-hops wireless communication systems with nonregenerative relays over flat Rayleigh-fading channels is presented. This is accomplished by deriving and applying some new closed-form expressions ...
Asymptotic BER analysis of FSO with multiple receive apertures over M-distributed turbulence channels with pointing errors
(
Optical Society of American (OSA)
, 2014 , Article)
In this paper, we consider a free-space optical (FSO) communication with multiple receive apertures over M-distributed turbulence channels with pointing errors. In particular, we consider two different combining schemes ...
Performance Analysis of Amplify-and-Forward Hybrid Satellite-Terrestrial Networks with Cochannel Interference
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider an amplify-and-forward hybrid satellite-terrestrial co-operative network in the presence of cochannel interference (CCI). More specifically, we assume that both the satellite-destination and the ...
Coverage, Probability of SNR Gain, and DOR Analysis of RiS-Aided Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
Recent studies have shown that reconfigurable Intelligent surfaces (RiSs) can help In extending the wireless coverage. However, no work has quantitatively analyzed the coverage. In this letter, we present the coverage ...
Interference management schemes with general order statistics and interference constraint for multi-user cooperative wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
In this paper, two cooperative communications schemes with interference management are proposed for multiuser wireless networks. The first scheme (Interference Constraint based Relay Selection (ICRS)) maximizes the received ...
Performance analysis of selective cooperation in amplify-and-forward relay networks over identical Nakagami-m channels
(
Wiley Online Library
, 2013 , Article)
In cooperative communications, multiple relays between a source and a destination can increase the diversity gain. Because all the nodes must use orthogonal channels, multiple-relay cooperation becomes spectrally inefficient. ...
Exact closed form expressions for outage probability of GSC receivers over Rayleigh fading channel subject to self-interference
(
IEEE
, 2010 , Conference Paper)
Previous work on performance analyses of generalized selection combining (GSC) RAKE receivers based on the signal to noise ratio focused on the development of methodologies to derive exact closed-form expressions for various ...
Secrecy Performance Analysis of RIS-Aided Wireless Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-aided wireless communication system in the presence of an eavesdropping user. Specifically, we assume that the RIS is placed ...
