Development of intelligent traffic light
(Universiti Malaysia Perlis, 2007-04)
Today, most of the traffic lights in Malaysia are controlled by Programmable Logic
Control (PLC). This controller is chosen due to its low cost and user friendly programming language. The program could be modified to suit ...
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). ...
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, ...
Performance analysis of multipath routing based on source routing
(Universiti Malaysia Pahang (UMP), 2009-06-20)
Mobile AdHoc Networks
(MANETs) is a collection of mobile hosts
forming a temporary network without the aid of
any established infrastructure or centralized
administration, and they interact with each other
over wireless ...
Clear fluid detector using Optical technique
(Universiti Malaysia Perlis, 2007-04)
Nowadays, the optical technologies are very young in Malaysia. This technology still in the research to changes the sensor technologies. The detector requirement are very similar to those of optoelectronic sources; that ...
Improving bit error rate of OCDM system using direct detection technique
(Universiti Malaysia Pahang (UMP), 2009-06-20)
A new detection technique, namely direct detection technique in OCDM system is introduced in this paper. In OCDM system, the unique code sequence is formed by using spectral components which are inherently arranged. The ...
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 encoder and decoder modules
(Universiti Malaysia Perlis, 2007-05)
A desirable feature for future optical networks would be the ability to process information directly in the optical domain for purposes of multiplexing, demultiplexing, filtering, amplification, and correlation. Optical ...
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 ...
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 ...
