On the degrees of freedom of the cognitive broadcast channel
(2011 , Conference Paper)
Cognitive broadcast channel, where two multiantenna transmitters communicate with their respective receivers, is considered. One of the transmitters is said to be cognitive (secondary) as it is assumed to know the messages ...
EEG-based automatic epilepsy diagnosis using the instantaneous frequency with sub-band energies
(
IEEE
, 2011 , Conference Paper)
This paper presents a novel approach for classifying the electroencephalogram (EEG) signals as normal or abnormal. This method uses features derived from the
instantaneous frequency (IF) and energies of EEG signals in ...
The 100 most influential persons in history": A data mining perspective
(2011 , Conference Paper)
Data mining has been widely applied in various domains; however, there have been limited studies into discovering hidden knowledge from factual data about selected groups of people with special characteristics. It is ...
Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
(
IEEE
, 2011 , Conference Paper)
The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ...
Assessment of fault-ride through capability of grid-connected brushless DFIG wind turbines
(
Institution of Engineering and Technology
, 2011 , Conference Paper)
DFIGs are reported to suffer serious reliability problems due to the presence of slip-rings, brushes and gearbox. These disadvantages encouraged several research groups to investigate the viability of employing single-frame ...
A synchronous DQ frame controller via an LCL coupled filter under unbalanced three-phase voltage supply conditions
(
IEEE
, 2011 , Conference Paper)
This paper proposes a synchronous DQ frame current controller for inverter based interfaced systems. The grid voltage may be unbalanced, possibly due to unequal line impedance. The output active and reactive powers oscillate ...
The ICDAR2011 Arabic writer identification contest
(
IEEE
, 2011 , Conference Paper)
Arabic writer identification is a very active research field. However, no standard benchmark is available for researchers in this field. The aim of this competition is to gather researchers and compare recent advances in ...
Harmonic rejection using multi-synchronous reference frame technique for CSI-based distributed generation with grid voltage distortion
(
IEEE
, 2011 , Conference Paper)
In the midst of the growing penetration of renewable energy resources and Distributed Generation (DG), power quality is one of the main concerns. Achieving low total harmonic distortion (THD) of exported current using low ...
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
(
IEEE
, 2011 , Conference Paper)
We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ...
Analysis of the time-varying cortical neural connectivity in the newborn EEG: A time-frequency approach
(
IEEE
, 2011 , Conference Paper)
Relationships between cortical neural recordings as a representation of functional connectivity between cortical brain regions were quantified using different time-frequency criteria. Among these, Partial Directed Coherence ...
