Multiple antenna cyclostationary-based detection of primary users with multiple cyclic frequency in Cognitive Radios
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the problem of multiple antenna spectrum sensing by using cyclostationary features of Primary Users (PUs) signals in Cognitive Radios (CRs). We consider the general case of multiple antenna sensing ...
A general multicompartment lung mechanics model with nonlinear resistance and compliance respiratory parameters
(
IEEE
, 2014 , Conference Paper)
In this paper, we develop a nonlinear multicompartment lung mechanics model that accounts for nonlinearities in both the airway resistances and the lung compliances. Many models assume that the airway resistances for a ...
Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error
(
IEEE
, 2014 , Conference Paper)
In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...
Open and closed-loop motor control system with incipient broken rotor bar fault detection using current signature
(
IEEE
, 2014 , Conference Paper)
Motor drive system is considered the most important asset in industrial applications. Detection of broken rotor bars has long been important but difficult job in detection area of incipient motor faults. The need for highly ...
An LCL filter-based grid-interfaced three-phase voltage source inverter: Performance evaluation and stability anaylsis
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
Power converters in grid connection applications commonly employ Sinusoidal Pulse-Width Modulation (SPWM) technique. Passive filters are employed in order to attenuate the generated switching current ripples and reduces ...
Robust Hybrid EKF approach for state estimation in multi-scale nonlinear singularly perturbed systems
(
IEEE
, 2014 , Conference Paper)
In this paper a general framework is developed for state estimation in a class of nonlinear continuous-time singularly perturbed systems. Our approach is based on the hybrid extended Kalman filter in which observations are ...
Optimized micro-climate controller of a greenhouse powered by photovoltaic generator
(
IEEE
, 2014 , Conference Paper)
Energy resources and food security are the most important issues for many countries around the world. Climatic conditions affect the agriculture production which is the backbone of the food security for all countries. ...
Phase noise mitigation in OFDMA uplink
(
IEEE
, 2014 , Conference Paper)
This paper addresses the problem of the phase noise induced spectral spread in an OFDMA uplink scenario. Accompanied with power differences between the users at the receiver in a multiuser case, the phase noise induced ...
ANN-based system for a discrimination between unbalanced supply voltage and phase loss in induction motors
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
It is documented that almost 98% of all voltage generated by electric utilities has up to 3% unbalance. Single phasing fault deserves special attention since phase loss is considered the worst case of unbalanced supply ...
On the correlation analysis of electric field inside jet engine
(
IEEE
, 2014 , Conference Paper)
A Simple channel modeling method based on correlation analysis of the electric field inside jet engine is presented. The analysis of the statistical propagation characteristics of electromagnetic field inside harsh jet ...
