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 ...
Life is engineering program: Impact of an engineering outreach project in K-12
(
IEEE
, 2013 , Conference Paper)
The demand for qualified national engineers is high in Qatar; Currently, a wide gap in supply exists. Consequently, urgent and proactive interventions at K-12 level to promote engineering profession to school students are ...
Performance analysis of relay selection schemes in underlay cognitive networks with imperfect channel state information
(
IEEE Computer Society
, 2013 , Conference Paper)
Cognitive Radio (CR) aims to improve spectrum utilization by allowing unlicensed users to access the licensed spectrum and to coexist with primary user (PU) while respecting the PU's restrictions. An interesting case to ...
Skills of engineers in knowledge based economies: A comprehensive literature review, and model development
(
IEEE
, 2013 , Conference Paper)
Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. In this paper, authors report on a systematic literature review on this issue. Findings of the review are spanned over two ...
Systemic framework of competencies of 21st century technical and engineering human resource: A development case for a knowledge based Economy in Qatar
(
IEEE
, 2013 , Conference Paper)
The required talent of 21st century engineering and technology human resource is significantly different and more complex than what has been needed ever before. Numerous relevant studies have been conducted during the last ...
Performance analysis of OFDMA based wireless cooperative networks with interference management
(
IEEE
, 2013 , Conference Paper)
In this paper, two cooperative communications schemes with interference management are proposed for orthogonal frequency division multiple access (OFDMA) based wireless networks. The first scheme maximizes the received ...
Multi-resampling Doppler compensation in cooperative underwater OFDM systems
(
IEEE
, 2013 , Conference Paper)
We consider a multi-carrier cooperative underwater acoustic communication (UWAC) system and investigate the Doppler scaling problem arising due to the motion of different nodes. Specifically, we assume an orthogonal frequency ...
Outage performance of OFDM-based relaying systems under IQ imbalance
(
IEEE
, 2013 , Conference Paper)
In the presence of different IQ imbalance (IQI) levels in the different nodes of a cooperative system, it becomes necessary to investigate the effect of each imbalance parameter on the performance. In this contribution, ...
Cooperative communications scheme with interference management under ICI for OFDM LTE-A systems
(
IEEE Computer Society
, 2013 , Conference Paper)
In long term evolution (LTE) systems, the achievable cell spectral efficiency is often limited by the inter carrier interference (ICI) or coverage shortage of base stations. Hence, in LTE-Advanced, cooperative communication ...
Performance analysis of relay selection schemes in OFDM-based underlay cognitive networks
(
IEEE
, 2013 , Conference Paper)
Cognitive radio (CR) is a promising technology that allows wireless systems to sense the environment and learn from previous experience to improve the communication quality. However, CR needs a flexible and adaptive physical ...
