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, ...
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 ...
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 ...
Performance analysis of optical zero cross correlation in OCDMA system
(Asian Network for Scientific Information, 2007)
We propose a new code structure for Spectral-Amplitude Coding Optical Code Division Multiple Access (OCDMA) systems with zero cross-correlation and theoretically demonstrate the performance of this code by using a direct ...
Equation-based construction technique for the OSCDMA zero cross correlation code for the basic matrix
(Institute of Electrical and Electronics Engineering (IEEE), 2007-05)
In this paper the Double Weight code (DW) family which is used as a proposed code in optical spectral code division multiple access system (OSCDMA) has been studied using the Modified Double Weight code (MDW) which has ...
New code structure for spectral amplitude coding in OCDMA system
(The Institute of Electronics, Information and Communication Engineers, 2007)
A new code structure for spectral amplitude coding optical code division multiple access system, based on Double Weight (DW) code families is proposed. The DW code has a, fixed weight of two. Modified Double Weight (MDW) ...
Performance of OCDMA systems using a complementary subtraction technique
(Optical Society of America, 2007)
What we believe to be a new code structure to reduce the multiple access interference in a spectral amplitude coding optical code-division multiple access system based on double-weight code families is proposed. Enhanced ...
Redesign the 4:2 compressor for partial product reduction
(International Association of Science and Technology for Development (IASTED) / ACTA Press, 2007)
In this paper, we attempt to redesign the 4:2 compressors. Since its inception by Weinberger in 1981[1], this concept of compressor has been used in most digital multiplications and multi operand operation scheme. The ...
Construction of a new code for spectral amplitude coding in optical code-division multiple-access systems
(Society of Photo-Optical Instrumentation Engineers (SPIE), 2007-07)
An enhanced code structure for spectral amplitude coding in optical code division multiple access systems based on double weight (DW) code families is proposed. Enhanced double weight (EDW) codes possess ideal cross-correlation ...
Spectral amplitude coding OCDMA using and subtraction technique
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
A new detection scheme, namely AND subtraction technique is proposed and presented in this paper. The theory is being elaborated and experimental results have been done by comparing Double-Weight (DW) code against the ...
