Design considerations of high performance optical code division multiple access: A new spectral amplitude code based on laser and light emitting diode light source
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid, Prof. Madya; R. Badlishah, Ahmad, Prof. Madya Dr. (The Institution of Engineering and Technology, 2010-02-01)A new code of optical code division multiple access (OCDMA) based on spectral amplitude coding (SAC) is described and analysed. The coding technique is called random diagonal (RD) code. One of the important properties of ... -
Improving bit error rate of OCDM system using direct detection technique
Sharifah Zarihan; Syed Alwee Aljunid, Syed Junid, Prof. Madya; Dayang Khadijah, Hamzah (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 ... -
Performance analysis of multipath routing based on source routing
N. Z., Ali; R. Badlishah, Ahmad, Prof. Madya Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Madya (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 ... -
Spectral amplitude coding OCDMA: Performance analysis on detection schemes using vectors combinatorial code families
Hasaan Yousif, Ahmed; Ibrahima, Faye; Saad, N. M.; Syed Alwee Aljunid, Syed Junid, Prof. Madya (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, ... -

Rashidi, C. B. M.; Anuar, Mat Safar; Syed Alwee Aljunid, Syed Junid, Prof. Madya (Institute of Electrical and Electronics Engineers (IEEE), 2010-05-11)This paper investigates the performance of direct detection technique for zero cross correlation code in Optical Code Division Multiple Access (OCDMA) which is a better technique to reduce Multi Access Interference (MAI). ... -
Triple-play services using random diagonal code for spectral amplitude coding OCDMA systems
Hilal Adnan, Fadhil; Syed Alwee Aljunid, Syed Junid, Prof. Madya; R. Badlishah, Ahmad (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 ...
