A minorization-maximization algorithm for an-based mimome secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
We consider the problem of secrecy rate maximization in a multi-input multi-output multi-eavesdropper (MIMOME) wiretap channel and present an exact solution. A general system model with a multi-antenna eavesdropper and a ...
Precoded spatial modulation for the wiretap channel with relay selection and cooperative jamming
(
Institute of Electrical and Electronics Engineers Inc.
, 2017 , Conference Paper)
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 ...
Novel cooperative policy for cognitive radio networks: Stability region and delay analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We consider a cognitive radio system that consists of primary user, secondary user, and their destinations. The secondary user has a relaying capability, i.e., it transmits the relayed packets from the primary user. Unlike ...
A hybrid TDMA-MAC cooperative relaying scheme: Stability and delay analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We consider a cooperative relaying system with any number of source terminals, one shared relay, and a common destination. We assume a slotted time division multiple access (TDMA) framework in which each source terminal ...
Cognitive relaying in wireless sensor networks: Performance analysis and optimization
(
IEEE
, 2010 , Conference Paper)
The anticipated increase in the density of the deployed wireless sensor networks calls for spectrum sharing through unlicensed access to licensed spectrum. The key technology for spectrum sharing in this scenario is cognitive ...
Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ...
The impact of authentic complex engineering design experience for k-12 students on 21st century attributes and perceptions towards STEM fields (Evaluation, Strand 3)
(
American Society for Engineering Education
, 2015 , Conference Paper)
Recent studies showed that embedding engineering at K-12 level has a positive impact on stimulating interest in- and improving learning outcomes of science and mathematics, and development of 21st Century skills. Engineering ...
Enhancing wireless networks performance through cooperative communications with interference management
(
IEEE
, 2012 , Conference Paper)
Cooperative radio communication has been proposed as an efficient technique to extend coverage and improve throughput in future wireless networks. However, its performance gain is degraded in the presence of co-channel ...
On the Ergodic Secrecy Rate of Massive MIMO Transmission with Partial Legitimate User CSI
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Conference Paper)
In this paper, we consider the downlink transmission over a single-cell massive multiple-input-multiple-output (MIMO) system in the presence of multiple single-antenna eavesdroppers (massive MIMOME). We concentrate on the ...
Area spectral efficiency of underlay cognitive radio transmission over rayleigh fading channels
(
IEEE
, 2013 , Conference Paper)
Cognitive radio is a promising technology to improve the spectrum utilization by allowing the unlicensed (secondary) user share a frequency bandwidth with the licensed (primary) owner under the condition that no harmful ...
