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 ...
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 ...
On ergodic capacity of wireless transmission subject to poisson distributed interferers over rayleigh fading channels
(
IEEE
, 2013 , Conference Paper)
Poisson point process has been widely adopted in the analysis of co-channel interference in dense frequency reuse systems. With the decaying power law, the aggregate co-channel interference in Poisson field can be viewed ...
Novel cooperative communication schemes with interference management for multi-user wireless networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Cooperative communication is a promising technique for future wireless networks. It can be used in improving communication reliability, and enhancing power and spectrum efficiency. However, its performance gain degrades ...
