Spectral amplitude coding OCDMA: Performance analysis on detection schemes using vectors combinatorial code families
(Fachverlag Schiele and Schoen GmbH, 2009)
In Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) system, Multip-user Interference (MUI) problem which increases with the number of users severely limits the performance of the system. However, ...
Triple-play services using random diagonal code for spectral amplitude coding OCDMA systems
(Fachverlag Schiele and Schoen GmbH, 2009)
In this paper, a new code called Random Diagonal (RD) code for spectral amplitude coding optical code division multiple access (OCDMA) networks is presented. This code is compared with other codes like MQC, MFH and Hadamard ...
Improving BER using RD Code for spectral amplitude coding optical CDMA network
(Institute of Electrical and Electronics Engineering (IEEE), 2009)
A new code for spectral-amplitude coding optical code-division multiple-access system is proposed called random diagonal (RD) code. This code is constructed using code segment and data segment. One of the important properties ...
The analytical design of a folded waveguide traveling wave tube and small signal gain analysis using madey's theorem
(Progress In Electromagnetics Research (PIER), 2009)
We are developing an analytical model for the design of the folded waveguide traveling wave tube (FWTWT). This analytical model provides the physical view for rapid design optimization of the FWTWT. The design and analysis ...
Low power reconfigurable sub-band filter bank ASIC for MP3 decoder
(Inderscience Publishers, 2009)
There is an ever demanding need to develop low power audio devices using MP3 technology. From the profiled results of MP3 algorithm on ARM processors, it has been observed that the synthesis filter bank in the audio decoder ...
Intelligent electronic nose system for basal stem rot disease detection
(Elsevier, 2009-05)
The agricultural industry has been, for a long time, dependent upon human expertise in using odour for classification, grading, differentiating and discriminating different types of produce. Odour as a parameter of ...
Compact ultra-wide band microwave filter utilizing quarter-wave length short-circuited stubs with reduced number of vias
(John Wiley & Sons Inc., 2009-09)
We present here a novel pattern with compact size of ultra-wide band microstrip filter. The filter is originally modeled from five poles quarter-wavelength short-circuited stubs. It is then, transformed into a new compact ...
"Via-Less” UWB Filter using Patched Microstrip Stubs
(VSP (imprint of Brill), 2009)
This paper presents an Ultra-Wide Band (UWB) microstrip filter which is initially modeled from a quarter-wavelength short-circuited stubs, without the use of any vias. All vias that provide short circuit stubs are replaced ...
A flexible and reliable architecture for mobile agent security
(Science Publications, 2009)
Problem statement: Wireless application protocol is a protocol that makes it possible to surf the Internet from a cellular phone or other handheld wireless. Many of us that surf the Internet from home with a 56 kbps modem ...
Effects of the Random Diagonal code link parameters on the performance of an OCDMA scheme for high-speed access networks
(Elsevier Inc., 2009-06)
In this paper, we study the performance of optical code-division multiple access (OCDMA) systems using Random Diagonal (RD) code under various link parameters. This code which can be constructed using address segment and ...
