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 ...

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). ...

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, ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
