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, ...
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 ...
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 ...
Optical code sequences for spectral-amplitude-coding optical CDMA systems
(Universiti Malaysia Perlis (UniMAP), 2007-01)
OPTICAL SPECTRUM code-division
multiple-access (OSCDMA) is a
multiplexing technique adapted
from successful implementation in
wireless networks. In OSCDMA each
user is assigned with a code
sequence code that serves ...
Extraction of visual information from simplified raster images
(Universiti Malaysia Perlis (UniMAP), 2007-08)
Simplification of raster images, with
irrelevant details of a visual query,
eliminates most useless elements,
while retaining perceptually dominant
elements and shape, speeds up
queries. The simplification is widely ...
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 ...
New approach of Double Weight Code Family Detection using reduced set of Fiber Bragg Gratings
(Institute of Electrical and Electronics Engineering (IEEE), 2007)
To increase the number of users in the double weight (DW) code family, a mapping technique is applied. This mapping technique increases the number of users but at a cost of unfixed cross-correlation property. The complementary ...
