A divided spectrum balanced detection technique for intensity noisereduction in SAC OCDMA systems
Ahmed M., Alhassan; Nasreen, Badruddin, Dr.; Mohamad Naufal, Mohamad Saad; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (Elsevier GmbH, 2013-12)In this paper we propose a simple divided spectrum balanced detection (DSBD) for spectral amplitudecoding (SAC) optical code division multiple access (OCDMA) systems. SAC OCDMA systems are limited byphase induced intensity ... -
Impact of multi-diagonal code on high-speed spectral amplitude coding optical code division multiple-access networks
Thanaa Hussein, Abd.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Hilal Adnan, Fadhil, Dr.; Junita, Mohd Nordin; Mohamad Naufal, Mohamad Saad, Assoc. Prof. (Springer-Verlag, 2013-09)In this paper, we present the impact of the multi-diagonal (MD) code for high data rate in spectral amplitude coding optical code division multiple-access (SAC-OCDMA) networks. An MD code structure for SAC-OCDMA system is ... -
Intensity noise mitigation in SAC OCDMA systems using a divided spectrum balanced detection scheme
Ahmed M., Alhassan; Nasreen, Badruddin, Dr.; Mohamad Naufal, Mohamad Saad, Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2013-09)We propose the use of a divided spectrum balanced detection (DSBD) to reduce the intensity noise in spectral amplitude coding (SAC) OCDMA systems. Simulation results show several order of magnitude improvements in bit error ... -
Minimizing correlation effect using zero cross correlation code in spectral amplitude coding optical code division multiple access
Anuar, Mat Safar, Ir. Dr.; Syed Alwee Aljunid, Syed Junid, Prof. Dr.; Amir Razif Arief, Jamil Abdullah, Dr.; Junita, Mohd Nordin; Mohamad Naufal, Mohamad Saad, Assoc. Prof. (The Optical Society of Japan, 2012-01)The use of minimal multiple access interference (MAI) in code design is investigated. Applying a projection and mapping techniques, a code that has a zero cross correlation (ZCC) between users in optical code division ... -
Performance analysis of wavelength multiplexed SAC OCDMA codes in beat noise mitigation in SAC OCDMA systems
Ahmed M., Alhassan; Nasreen, Badruddin, Dr.; Mohamad Naufal, Mohamad Saad; Syed Alwee Aljunid, Syed Junid, Prof. Dr. (European Optical Society, 2013-07)In this paper we investigate the use of wavelength multiplexed spectral amplitude coding (WM SAC) codes in beat noise mitigation in coherent source SAC OCDMA systems. A WM SAC code is a low weight SAC code, where the whole ... -
