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 ...
Performance of the optical spectrum CDMA systems in FTTH access network
(Institute of Eelectrical and Electronics Engineering (IEEE), 2007-05)
Double Weight (DW) code is presented here to support fiber-to-the-home (FTTH) access network in point-to-multipoint (P2MP) applications. This code with basic fixed weight of 2 possess ideal cross correlation properties, ...
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 ...
Generalization performance analysis between fuzzy ARTMAP and Gaussian ARTMAP neural network
(Universiti Malaya, 2007)
This paper examines the generalization characteristic of Gaussian ARTMAP (GAM) neural network in classification tasks. GAM performance for classification during training and testing is evaluated using the k-folds cross ...
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 ...
A BI-RADS based expert systems for the diagnoses of breast diseases
(Science Publications, 2007)
We proposed an expert system based on the interpretation of mammographic and ultrasound images that may be used by expert and non-expert doctors in the interpretation and classifying of patient cases. The expert system ...
