Digital baseband compensation of frequency-dependent joint TX/RX I/Q imbalance in beamforming MIMO OFDM transceivers
(
IEEE
, 2012 , Conference Paper)
In this paper, we investigate the effects of asymmetric frequency-dependent joint transmit-receive I/Q imbalance on the performance of beamforming MIMO-OFDM systems. We derive the throughput-maximizing transmit/receive ...
SINR analysis for beamforming OFDM systems under joint transmit-receive I/Q imbalance
(
IEEE
, 2012 , Conference Paper)
In this paper, we derive an analytical expression for the subcarrier average SINR of a beamforming OFDM system in the presence of joint transmit-receive I/Q imbalance. The derived expression quantifies the impact of the ...
LingoSnacks: M-Learning platform for language learning
(
IEEE
, 2012 , Conference Paper)
This paper reports the experience of designing and developing a multimedia m-Learning platform (named LingoSnacks) for interactive learning of Arabic spelling and vocabulary. It uses interactive game-like delivery methods ...
Applying and evaluating architectural patterns on a stock trading case study
(
IEEE
, 2012 , Conference Paper)
Teaching architectural and design patterns is a difficult task and not easy to understand by the students as patterns are expressed at a higher abstraction level than programming language constructs or graphical UML ...
Security oriented service composition: A framework
(
IEEE
, 2012 , Conference Paper)
This paper argues that in order to address the challenges of security compatibility checking between the client's software and the service software in a service oriented software environment, the followings have to be ...
EasyCapstone: A framework for managing and assessing capstone design projects
(
IEEE
, 2012 , Conference Paper)
To enhance students learning and satisfy ABET requirements, the Department of Computer Science and Engineering at Qatar University undertook over the past few years significant enhancements to the senior design project ...
Modeling security importance and preferences of software services
(
IEEE
, 2012 , Conference Paper)
This paper proposes a modeling framework on how to specify security preferences and importance of software services, and compute a quantifiable value. Our approach advocates for an automatic calculation of the results of ...
An autonomic detection and protection system for denial of service attack
(
ACTA Press
, 2012 , Conference Paper)
This paper introduces a self-protection structure for computing system. The proposed structure aims to detect, classify and protect against DoS attacks. This architecture utilizes a model-based decision approach that ...
The Attitudes of Qatari Nationals and White-Collar Resident Workers Towards the New Traffic Law in Qatar
(2012 , Conference Paper)
In 2007 the government of Qatar enacted a new traffic law with the objectives of improving the traffic flow and reducing the road traffic-related death and accident rates in the country through policy interventions, mass ...
A/C condensate for water reuse: An approach towards environmental sustainability in Doha
(
American Society of Agricultural and Biological Engineers
, 2012 , Conference Paper)
A/C Condensate is a relatively untapped alternative source of water that might be readily available especially in hot arid climates. The objective of this study is to establish the feasibility of the A/C condensate as the ...
