Development of new OCDMA code
(Universiti Malaysia Perlis, 2007-05)
Nowadays, communication is very important at any place, time and situation. The transmission of signal can be in wireless or cable (especially fiber optic that has more advantages than others cable for a long distance). ...
Development of Optical Code Division Multiple Access (OCDMA) for Local Area Network (LAN)
(Universiti Malaysia Perlis, 2008-04)
Nowadays, communication is very important at any place, time and situation. The transmission of the signal can be in wireless or cable. There are three type of division multiple accesses that use in communication system ...
Development of new OCDMA detection scheme
(Universiti Malaysia Perlis, 2007-03)
A new direct detection technique is proposed for optical code multiple accesses using
Double Weight code. In optical system the detection process affect design transmitter and receiver. The Multiple Access Interference ...
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 ...
Development of point-to-point OCDMA system for metropolitan area network
(Universiti Malaysia Perlis, 2007-05)
Future telecommunication systems and networks are expected to provide a variety of integrated broadband services to the customers. There has been a tremendous interest in applying Code Division Multiple Access (CDMA) ...
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 ...
Spectral amplitude coding OCDMA using and subtraction technique
(Optical Society of America, 2008-03)
An optical decoding technique is proposed for a spectral-amplitude-coding- optical code division multiple access, namely, the AND subtraction technique. The theory is being elaborated and experimental results have been ...
The effects of MAC protocols on ad hoc on-demand distance vector (AODV) routing protocol
(Kolej Universiti Kejuruteraan Utara Malaysia, 2005-05-18)
Ad hoc networks play an important role in mobile radio networks due to its flexibility and low operation cost. Several of key research issues of ad hoc network are on the
routing and MAC algorithms. But, only a few of ...
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 ...
Performance of random diagonal code for OCDMA systems using new spectral direct detection technique
(Elsevier Inc, 2009-01-31)
This paper studies the performance of random diagonal (RD) code for spectral-amplitude coding OCDMA (SAC-OCDMA) system using a newly proposed spectral direct detection technique. RD code is constructed using code segment ...
