On relay assignment in network-coded cooperative systems
(
IEEE
, 2011 , Article)
We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other ...
Threshold-based relaying in coded cooperative networks
(
IEEE
, 2011 , Article)
In cooperative communications, error propagation at the relay nodes degrades the diversity order of the system. To combat that effect, we present a novel technique to control error propagation at the relays, which is ...
Inter-relay interference management schemes for wireless multi-user decode-and-forward relay networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, two cooperative communications schemes with inter-relay interference (IRI) management are proposed for wireless multi-user decode-and-forward (DF) relay networks. The schemes are based on a DF half-duplex ...
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 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. ...
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 ...
Precoding-Aided Spatial Modulation for the Wiretap Channel with Relay Selection and Cooperative Jamming
(
Hindawi Limited
, 2018 , Article)
We propose in this paper a physical-layer security (PLS) scheme for dual-hop cooperative networks in an effort to enhance the communications secrecy. The underlying model comprises a transmitting node (Alice), a legitimate ...
Joint optimal threshold-based relaying and ml detection in network-coded two-way relay channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2012 , Article)
In this paper, we address the problem of joint optimal threshold-based relaying and maximum likelihood (ML) detection in network-coded cooperative systems. The purpose of using threshold-based relaying is to circumvent the ...
Performance of Mixed RF/FSO with Variable Gain over Generalized Atmospheric Turbulence Channels
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this paper, we consider a free-space optical (FSO) communication scheme with the help of a variable gain relay where the links from the source to the relay are radio-frequency (RF) links while the links between the relay ...
