Investing in Research: Teaching the History of Qatar as An Example
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
The author of this presentation has mentor Undergraduate Research Experience program (UREP) projects. The projects' topics were directly related to social, political and commercial history of Qatar. Although, the main ...
Facebook: A potential educational tool in higher education
(
Hamad bin Khalifa University Press (HBKU Press)
, 2015 , Conference Paper)
Introduction: Facebook is the most frequently visited social media networking site worldwide (Ryan & Xenos 2011). Mason and Rennie (2007: 199) reasoned, "shared community spaces and inter-group communications are a massive ...
Adaptive network coding for spectrum sharing systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose an adaptive network coding scheme for cognitive relay networks comprising multiple secondary sources communicating with a common destination in the presence of multiple primary users. Conventional ...
Improved relay selection for decode-and-forward cooperative wireless networks under secrecy rate maximization
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Privacy and security have an increasingly important role in wireless networks. A secure communication enables a legitimate destination to successfully retrieve information sent by a source, while it disables the eavesdropper ...
Joint statistics of partial sums of ordered exponential variates and performance of GSC RAKE receivers over rayleigh fading channel
(
IEEE
, 2011 , Article)
Spread spectrum receivers with generalized selection combining (GSC) RAKE reception were proposed and have been studied as alternatives to the classical two fundamental schemes: maximal ratio combining and selection combining ...
Optimal power consumption based on new power spectral efficiency metric for wireless cellular networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new power spectral efficiency (PSE) metric, to quantify the spectral efficiency and the total required power to cover a certain area with a predefined received signal quality. This metric ...
Analysis of cell spectral efficiency of infrastructure relay-enhanced cellular system
(
IEEE
, 2011 , Conference Paper)
In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced cellular systems. In particular, we use the average achieved spectral efficiency at an arbitrary mobile receiver in presence ...
Effective area spectral efficiency metric for decode-and-forward cooperative wireless communications
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we introduce a new metric, namely: effective area spectral efficiency (EASE), to quantify the spectral efficiency as well as the spatial properties of decoding and forward (DF) relaying wireless communications ...
Capacity analysis of cognitive wireless networks with dynamic spectrum access
(
IEEE Computer Society
, 2015 , Conference Paper)
Cognitive radio (CR) is a promising technology based on spectrum sharing where the secondary unlicensed users can access the licensed frequency bands in the primary system without any modification to the devices, services ...
Performance analysis of selective cooperation in underlay cognitive networks over Rayleigh channels
(
IEEE
, 2011 , Conference Paper)
Underlay cognitive networks should follow strict interference thresholds to operate in parallel with primary networks. This constraint limits their transmission power and eventually the area of coverage. Therefore, it is ...
