Performance analysis of hybrid OCDMA/WDM system for metro area network
(Walter de Gruyter Berlin/Boston, 2014-03)
In this study a hybrid spectral amplitude coding for optical code division multiple access (i.e., called OCDMA) over wavelength division multiplexing (WDM) network is proposed to support large number of subscribers. The ...
High deadline meeting rate of non-preemptive dynamic soft real time scheduling algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
Hard real time systems were often implemented with preemptive scheduling, which gives priority to the highest priority task. In this paper we present a new non-preemptive scheduling of jobs meant for soft real time ...
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)
In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ...
Performance evaluation of Fi-Wi network based on SCM-optical code division multiple access architecture
(Elsevier GmbH, 2013-10)
This paper investigates the performance of a spectral amplitude coding (SAC)-OCDMA system design utilizing subcarrier multiplexing techniques for use in the popular fiber-wireless (Fi-Wi) technology. Zero cross correlation ...
Waveform design for improved range and Doppler resolution in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02)
The choice of a suitable transmit waveform is an important problem in radar design. This is so because the waveform controls resolution and clutter performance and also bears heavily on the system cost. Theoretical studies ...
Cognitive wireless sensor actor network: an agricultural perspective
(ICIC International, 2014-04)
Intelligent environments are exposing the next revolutionary steps of development technologies in automation of building, industrial, home, and transportation systems. The new generation of Wireless Sensor Actor Networks ...
An embedded network traffic monitoring system for portable applications
(Medwell Journals, 2013)
This study presents an enhanced Embedded Network Traffic Monitoring (ENTM) system capable of capturing and analyzing network traffic information on data networks. The system incorporates an enhanced packet probing subsystem ...
Electronically reconfigurable beam steering antenna using embedded RF PIN based parasitic arrays (ERPPA)
(EMW Publishing, 2013)
In this paper, an electronically reconfigurable beam steering antenna using embedded RF PIN switches based parasitic array (ERPPA) is proposed for modern wireless communication systems that operate at 5.8 GHz frequency. ...
Characteristic region based image steganography using Speeded-Up Robust Features technique
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Steganography is the art and science of invisible
communication. It is employed in different useful a
pplications,
like, safe circulation of secret data and Medical I
maging Systems.
For most of the current steganography ...
Design and simulation a new code with zero cross-correlation for SAC-OCDMA networks
(INSInet Publications, 2012-03)
Design and simulation of new code family for the Spectral Amplitude Coding-Optical Code Division Multiple Access (SAC-OCDMA) networks is present. The new code family called Multi Diagonal (MD) code. The MD code family ...
