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 ...
A component map tuning method for performance prediction and diagnostics of gas turbine compressors
(
Elsevier Ltd
, 2014 , Article)
In this paper, a novel compressor map tuning method is developed with the primary objective of improving the accuracy and fidelity of gas turbine engine models for performance prediction and diagnostics. A new compressor ...
Parameter identification of five-phase induction machines with single layer windings
(
IEEE
, 2014 , Article)
Despite the increased interest in multiphase induction machines for safety-critical applications, machine parameter identification for the different sequence planes is still a challenging research point. In most available ...
Opportunistic spectrum sharing in relay-assisted cognitive systems with imperfect CSI
(
IEEE
, 2014 , Article)
In this paper, we consider spectrum sharing between cognitive radio (CR) users and a licensed primary user (PU) to enhance the spectrum efficiency. In the considered scenario, the PU is not able to successfully transmit ...
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 ...
An interline dynamic voltage restoring and displacement factor controlling device (IVDFC)
(
IEEE
, 2014 , Article)
An interline dynamic voltage restorer (IDVR) is invariably employed in distribution systems to mitigate voltage sag/swell problems. An IDVR merely consists of several dynamic voltage restorers (DVRs) sharing a common dc ...
Stability analysis of an active-damped LLCL filter- based grid-connected three-phase inverter
(
IEEE
, 2014 , Conference Paper)
Power passive filters are a standard solution for gridcurrent harmonics attenuation. However, these types of filters may cause a resonance between the inverter and the grid. Passive and active damping techniques are employed ...
Fault detection and isolation of Fornasini-Marchesini 2D systems: A geometric approach
(
IEEE
, 2014 , Conference Paper)
The fault detection and isolation (FDI) problem for discrete-time two-dimensional (2D) systems represented by the Fornasini-Marchesini model II is investigated in this work. It is shown that the sufficient conditions for ...
Outage analysis of hybrid FSO/RF systems based on finite-state Markov chain modeling
(
IEEE
, 2014 , Conference Paper)
In this paper, we analyze the outage probability of a hybrid free-space optical/radio-frequency (FSO/RF) communication system with soft-switching. In soft-switching approach, either one of the links or both links can be ...
