A cost-effective method for high-quality 60GHZ optical millimeter wave signal generation based on frequency quadrupling
Nael Ahmed, Al-Shareefi; Syed Idris, Syed Hassan, Prof. Dr.; Mohd Fareq, Abd. Malek, Dr.; Razali, Ngah, Assoc. Prof. Dr. ; Sura A., Abbas; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (EMW Publishing, 2013)In this paper, we present a cost effective method to generate a high-quality quadruple frequency optical millimeter- wave (MMW) signal using an integrated dual-parallel Mach-Zehnder modulator (IDP-MZM). Not only does the ... -
New approach for evaluation of the performance of spectral amplitude coding-optical code division multiple access system on high-speed data rate
Thanaa Hussein, Abd.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr.; R. Badlishah, Ahmad, Prof. Dr.; Mohd Abdur, Rashid, Dr. (The Institution of Engineering and Technology, 2012-08-14)In this study, the authors proposed a new approach to evaluate the system performance of spectral amplitude codingoptical code division multiple access (SAC-OCDMA) systems. The system performance is evaluated based on a ... -
Performance enhancement of OCDMA system using NAND detection with modified double weight (MDW) code for optical access network
Nasim, Ahmed; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr.; R. Badlishah, Ahmad, Prof. Dr.; Mohd Abdur Rashid, Dr. (Elsevier GmbH, 2013-07)In this paper, we have extensively analyzed the OCDMA system performance using modified double weight (MDW) code with NAND detection technique as newly developed by the authors. In theoretical analysis, various noises and ... -
Performance improvement of spectral amplitude coding-optical code division multiple access systems using NAND detection with enhanced double weight code
Nasim, Ahmed; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; R. Badlishah, Ahmad, Assoc. Prof. Dr. (The Optical Society of Japan, 2012-01)The bit-error rate (BER) performance of the spectral amplitude coding-optical code division multiple access (SACOCDMA) system has been investigated by using NAND subtraction detection technique with enhanced double weight ...
