Performance evaluation of multi-component instantaneous frequency estimation techniques for heart rate variability analysis
(2012 , Conference Paper)
Accurate instantaneous frequency (IF) estimation of the non-stationary heart rate signal is important in quantifying the heart rate variability (HRV) measures. This study compares the effectiveness of four IF estimation ...
Performance analysis of relay selection schemes in underlay cognitive networks with Decode and Forward relaying
(
IEEE
, 2012 , Conference Paper)
In underlay cognitive networks with regenerative relaying, secondary users operating with primary user are adhering to stringent interference constraint which limits their transmission power and coverage area. In order not ...
ICFHR2012 competition on writer identification - Challenge 2: Arabic scripts
(
IEEE
, 2012 , 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 ...
A set of geometrical features for writer identification
(
Springer
, 2012 , Conference Paper)
Writer identification is an important field in the forensic document examination. We propose in this paper a set of geometrical features that makes it possible to characterize writers. They include directions, curvatures ...
Modified Alamouti decoding for highly selective channels for LTE systems
(
IEEE
, 2012 , Conference Paper)
In this contribution, we propose an improvement of Alamouti coding for equalization of space-time block code multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) over highly-selective ...
Cloud-Ready Biometric System for Mobile Security Access
(
Springer
, 2012 , Conference Paper)
In this contribution, we introduce an application that allows a mobile phone to be used as a biometric-capture device for secure access to the cloud. In this application, the biometric capture and recognition are performed ...
Multilevel cascaded Z source inverter for PV power generation system
(
IEEE
, 2012 , Conference Paper)
The paper investigates the use of multilevel cascaded Z source inverter (MC-ZSI) for photovoltaic (PV) power generation system. The control of the proposed system will take into account the multilevel modulation scheme and ...
Compressed wideband spectrum sensing with correlated subband occupancy in multi-antenna cognitive radios
(2012 , Conference Paper)
In this paper, we investigate the use of multiple antennas at the cognitive radio receiver for improved wideband spectrum sensing and exploit compressed sensing to reduce the extremely high sampling rate of wideband signal. ...
QUWI: An Arabic and English handwriting dataset for offline writer identification
(
IEEE
, 2012 , Conference Paper)
This paper presents a new offline dataset called the Qatar University Writer Identification dataset (QUWI). This dataset contains both Arabic and English handwritings and can be used to evaluate the performance of offline ...
Orthogonalized partial directed coherence for functional connectivity analysis of newborn EEG
(2012 , Conference Paper)
The aim of this study is to develop a time-frequency method and test its applicability to investigating directional cortical connectivity in the newborn brain considering the effect of volume conduction. We modified ...
