Generalized area spectral efficiency: An effective performance metric for green wireless communications
(
IEEE
, 2014 , Article)
Area spectral efficiency (ASE) was introduced as a metric to quantify the spectral utilization efficiency of cellular systems. Unlike other performance metrics, ASE takes into account the spatial property of cellular ...
Wavelet Denoising Based on the MAP Estimation Using the BKF Prior With Application to Images and EEG Signals
(
IEEE
, 2013 , Article)
This paper presents a novel nonparametric Bayesian estimator for signal and image denoising in the wavelet domain. This approach uses a prior model of the wavelet coefficients designed to capture the sparseness of the ...
Relay selection in underlay cognitive networks with fixed transmission power nodes
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ...
On the Design of Bit-Slice Processors
(
Qatar University
, 1988 , Article)
In the past decade, fixed instruction microprocessors have evolved from 4 bits to 32 bits. Their compact design and relative low cost have made them very popular with design engineers. Their use extends into a lot of ...
Performance Evaluation of A Class of Adaptive Bifurcated Routing Algorithms
(
Qatar University
, 1988 , Article)
With the cost of computation decreasing, packet-switched computer communication networks are becoming increasingly cost effective. In this paper a class of bifurcated routing algorithms is considered. One of the algorithms ...
Multi-component instantaneous frequency estimation using locally adaptive directional time frequency distributions
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper presents a locally adaptive time-frequency (t,f) method for estimating the instantaneous frequency (IF) of multi-component signals. A high-resolution adaptive directional time-frequency distribution (ADTFD) is ...
Comments on: "Fault detection for continuous-time switched systems under asynchronous switching"
(
John Wiley & Sons, Ltd.
, 2015 , Article)
In this note, a defect occurred in Theorem 1 in the study Du et al. (Int. J. Robust Nonlinear Control 2013; doi: 10.1002/rnc.2961) is addressed. Additionally, the correction of the theorem is presented.
A methodology for time-frequency image processing applied to the classification of nonstationary multichannel signals using instantaneous frequency descriptors with application to newborn EEG signals
(
Springer
, 2003 , Article)
This article presents a general methodology for processing non-stationary signals for the purpose of classification and localization. The methodology combines methods adapted from three complementary areas: time-frequency ...
Mitigating error propagation in two-way relay channels with network coding
(
IEEE
, 2010 , Article)
In relay networks, error propagation at the relay nodes degrades the performance of the system. To combat that effect, it has been suggested to implement a reliability threshold at the relay to control error propagation. ...
A Mechanistic Neural Field Theory of How Anesthesia Suppresses Consciousness: Synaptic Drive Dynamics, Bifurcations, Attractors, and Partial State Equipartitioning
(
Springer Verlag
, 2015 , Article)
With the advances in biochemistry, molecular biology, and neurochemistry there has been impressive progress in understanding the molecular properties of anesthetic agents. However, there has been little focus on how the ...
